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 force acting on a charged particle q moving with a velocity in a uniform magnetic field?
Moving Charges And Magnetism. What is direction of force acting on a charged particle q, moving with a velocity u in a uniform magnetic field B? The
force is acting in a sideways direction, perpendicular to both the velocity and the ,agnetic field
. The direction of force is given by the right hand rule.
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.
What is the direction of force in an electric field?
The direction of the electric field is always directed in
the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge
. Since electric field is a vector quantity, it can be represented by a vector arrow.
What is the direction of force of friction acting on a moving object?
The direction of frictional force is
always opposite to the direction of motion
. Friction always tends to oppose the applied force.
What is the direction of the magnetic force on a positive charge that moves as shown in Figure 22.50 E below )?
22.7 MAGNETIC FORCE ON A CURRENT-‐CARRYING CONDUCTOR
36.
Which direction does the frictional force always act?
An important property of friction is that it always acts
in the direction opposite to the direction of motion
i.e. if an object is moving from left to right, the frictional force acts on it from right to left and vice versa. A car moving from right to left stops when brakes are applied.
What is the direction of the magnetic force on the current in each of the six cases shown in the following figures?
The direction of this force is given by
RHR-1
, with the thumb in the direction of the current I. Then, with the fingers in the direction of B, a perpendicular to the palm points in the direction of F, as in Figure 2.
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 direction of the magnetic force on the proton?
Direction is given by cross product of the velocity and magnetic field vectors
(right hand rule)
and is due south. Second proton is travelling North with speed of 8.0×105m/s. And the magnetic field is 0.3T going east.
What is the direction of the electric field at a point directly to the left of a positive charge?
The electric field points to the left because the force on a negative charge is opposite to the direction of the field. The electric field points to the right because the force on a negative charge is in the same direction as the field.
When using the right hand rule to determine the direction of the magnetic force on a charge which part of the hand points in the direction that the charge is moving quizlet?

velocity, fingers point in direction of magnetic (B) field, palm points in the direction of the acting force. You just studied 5 terms!
What is the direction of force on a positive charge when entering a uniform magnetic field B in the direction indicated?
The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the
right hand point in the direction of v
, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.
What direction is the force on a positive charge when entering a uniform B?
So we can say that the electric force because the charges positive, so the electric force will point
out in the direction of electric field
. So we can say that the net force will point out in the inward direction okay, inward direction, or it can be written as into the piece, into the piece.
Under what condition is the force acting on a charge moving through a uniform magnetic field maximum?
Force is maximum
when sin θ=1 or θ=90

What is the force acting on a charged particle Q?
Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by
F = qE + qv × B
.
How does the curve of a charged particle show whether it is charged positive or negative?
The positive and negative charges will
curve in perpendicular directions
that can be determined using the left-hand rule governing electromagnetic interactions. The positive and negative charges will curve in opposite directions that can be determined using the right-hand rule governing electromagnetic interactions. …
What is Fleming’s left hand rule?
Fleming’s left – hand rule states that
if we stretch the thumb, middle finger and the index finger of the left hand in such a
way that they make an angle of 90 degrees(Perpendicular to each other) and the conductor placed in the magnetic field experiences Magnetic force.
