perpendicular to
both the wire and the magnetic field with direction given by the right hand rule.

point the thumb of the right hand in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F
.
What is the force on a current-carrying wire in a magnetic field?

The magnetic force on a current-carrying wire is
perpendicular to both the wire
and the magnetic field with direction given by the right hand rule.
How do you know the direction of force on a wire?
You can find it by
pointing your right thumb in the direction of the current in the wire and curling your fingers
. Your fingers will be curled in the same direction as the magnetic field around the wire.
How do you find direction?
The sun rises in the general direction of
east
and sets in the general direction of west every day, so you can use the location of sunrise or sunset to get an approximate idea of direction. Face the sunrise and you are facing east; north will be on your left and south will be on your right.
What is the direction of the current flowing through the wire left or right?
The direction of an electric current is by convention the direction
in which a positive charge would move
. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
What is the direction of the magnetic field created by the wire at the location of the point charge?
Use the right-hand rule: the thumb goes upwards with the conventional current of the wire. This means the magnetic field will be going
counter-clockwise
when viewed from the top. At the location of the charge, the magnetic field points out of the screen.
What is the direction of the magnetic field at the location of the charge due to the current carrying wire?
The direction of the field is determined by the
right-hand
rule. If the wire is horizontal and the current is to the left, then the magnetic field will be directed into the page at a point above the wire and out of the page at a point under the wire (please see the attached image).
What is the direction of the magnetic force on the wire if the current flows from east to west?
Maxwell’s right hand thumb rule states that, when the current flows from east to west direction, the magnetic field will move in a
clockwise direction
, that is, from the direction north to south.
What is the direction of force that is exerted on a current carrying conductor kept perpendicular in external magnetic field?
A current carrying conductor placed in a magnetic field experiences a force. If the direction of the field and that of current are mutually perpendicular to each other, then the force acting on the conductor will be
perpendicular to both
and that can be determined using the Fleming’s left-hand rule.
What is the direction of force between two parallel wires carrying current in opposite direction?
Two parallel wires carrying current in opposite directions
repel
and try to move away from each other.
What is Palm rule?
If we
hold the thumb of the right hand mutually perpendicular to the grip of the fingers
such that the curvature of the finger represents the direction of current in the wire loop, then the thumb of the right hand will point in the direction of the magnetic field near the center of the current loop.
How do you find the direction of an electric field?
electric field is
always directed from positive to negative potential
. if your test charge is move away from positive potential then force is in the direction of electric field and if test charge is moving towards positive potential then force in direction opposite to electric field.
In what direction is West?
Most maps show North at the top and South at the bottom.
To the left is West
and to the right is East.
What direction means?
noun.
the act or an instance of directing
. the line along which anything lies, faces, moves, etc., with reference to the point or region toward which it is directed: The storm moved in a northerly direction. the point or region itself: The direction is north.
What direction is conventional current?
The direction of conventional current is from
the positive terminal, through the conductor, to the negative terminal
. The direction of free electron flow is from the negative terminal, through the conductor, to the positive terminal. The direction of conventional current is the direction marked on all circuit diagrams.
Where is the East and West?
East and west are
at right angles to north and south
. East is in the clockwise direction of rotation from north. West is directly opposite east. The sun’s position in the sky can be used to determine east and west if the general time of day is known.
Why current direction is opposite to electron flow?
Electrons being negatively charged flow from the negative terminal to the positive terminal of the voltage source. So, the actual direction of current should be from negative to positive terminal. … So, the current flow is considered in the direction opposite to the direction of flow of electrons.
What is the direction of the magnetic field lines?
The lines are directed from
north pole to the south pole outside the magnet
while they are directed from south pole to north pole inside the magnet. A tangent drawn on a magnetic field line gives the direction of the magnetic field at that point.
What is the direction of a magnetic field *?
The direction of magnetic field lines is defined to be the
direction in which the north end of a compass needle points
. The magnetic field is traditionally called the B-field.
What is the direction of magnetic field at any point?
The direction of the magnetic field is
tangent to the field line
at any point in space. A small compass will point in the direction of the field line. The strength of the field is proportional to the closeness of the lines.
What is the magnitude B of the magnetic field?
Equation :
B=2πRμ0
i gives the magnitude B of the magnetic field set up by a current in an infinitely long straight wire, at a point P at perpendicular distance R from the wire.
What is the magnitude of the net force on the first wire in?
The magnitude of the net force on the first wire is
2.5 × 10
– 4
N
.
Can two magnetic field lines cross?
Magnetic field lines can never cross
, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end.
When conductor carry the current in the opposite direction then?
Detailed Solution. The force between these two parallel conductors is attractive if the current is flowing in the same direction. If the current is flowing in the opposite direction,
the force between them is repulsive
.
In which direction is the magnetic force acting on the charge quizlet?
A magnetic force is exerted on an electric charge moving through a uniform magnetic field. The direction of the magnetic force acting on a moving electric charge in a magnetic field is
perpendicular to the direction of motion
. A magnetic force is exerted on a stationary electric charge in a uniform magnetic field.
What is the direction of the magnetic field if current is induced in vertically up on moving the conductor towards East?
Answer: Since the change in flux is increasing in the upwards direction, Lenz’s law tells us that the induced current’s induced magnetic field must resist that, and point downwards on the inside of the loop. Using the right hand rule, we can see that we end up with an induced current in the
clockwise direction
.
What is the force between two parallel current carrying wires?
The official definition of the ampere is: One ampere of current through each of two parallel conductors of infinite length, separated by one meter in empty space free of other magnetic fields, causes a force of
exactly 2 × 10
− 7
N/m
on each conductor.
How do you find the force between two parallel wires?
- The force between two parallel currents I1 and I2 separated by a distance r, has a magnitude per unit length given by Fl=μ0I1I22πr.

How will you find the direction of the force experienced by a current carrying conductor placed in the magnetic field?
The right-hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v),

When a conductor is placed in force is exerted on it?
When a current carrying conductor is placed in a
