The magnitude of the force is F = qvB sin(θ). The direction of the force is given by the right-hand rule. The force exerted on a charge moving in a magnetic
field is always perpendicular to both the velocity and the
field. … All it can do is make the charge change direction.
What happens when two current carrying wires are perpendicular to each other?
Any current-carrying wire creates a
magnetic field
around itself and this magnetic field can exert a force on another wire with another current. The force due to the magnetic field is perpendicular to both magnetic field and the current direction and is proportional to both current and magnetic field.
Do perpendicular wires have force?
Do perpendicular wires exert force on each other?
Yes
. Two wires repel each other when carrying current in opposite directions—the force on each wire is equal in magnitude and opposite in direction. correct Perpendicular wires exert no net force on one another, but there will be a torque.
What is the force on a wire moving perpendicular to a magnetic field?
If a straight conducting wire is placed in a plane perpendicular to a uniform magnetic field, and is moving in a direction perpendicular to the field, then each charge q in the wire experiences a magnetic force of
magnitude F = qvB
. The negatively charged electrons will accelerate in response to this force.
Is current perpendicular to magnetic force?
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.
What happens when force is perpendicular to velocity?
When a force is applied to a moving object, there is no deacceleration therefore, the linear speed remains constant. But, the
velocity vector changes direction and will be pulled towards the direction of the force
.
Why is the Lorentz force perpendicular?
The superficial answer is simply that the Lorentz (magnetic) force is proportional to v×B, where v is the particle velocity and B is the magnetic field.
Since the vector cross product is always at right angles to each of the vector factors
, the force is perpendicular to v.
What is the force between two perpendicular current carrying wires?
Two wires repel each other when carrying current in opposite directions—the force on each wire is equal in magnitude and opposite in direction. correct Perpendicular wires exert no net force on one another, but there will be
a torque
. — There will be no net force on the wires, but there will be a torque.
What is a motional emf?
An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the equation
emf = LvB
, where L is length of the object moving at speed v relative to the strength of the magnetic field B.
Why is current perpendicular to a magnetic field?
The magnetic field is the Lorentz transform of the electric field. If we boost to the reference frame of the moving charges in your current, an electric field will emerge. The resulting
electric force
is perpendicular to both the magnetic field and the velocity of the charges in the current.
Which electromagnet is the strongest?
Bitter electromagnets
have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas, as of 2011.
How do you determine the direction of a magnetic force?
The right hand rule
Which force is perpendicular to velocity?
Centripetal force
is perpendicular to velocity and causes uniform circular motion. The larger the F
c
, the smaller the radius of curvature r and the sharper the curve. The second curve has the same v, but a larger F
c
produces a smaller r′.
Does a perpendicular force change velocity?
Suppose an object is moving at some veocity v. Why is it that if you apply a force in the direction perpendicular to the direction of velocity, you only change the direction of the velocity and not its magnitude.
Why acceleration is perpendicular to velocity?
Acceleration that is perpendicular to velocity
changes ONLY the velocity’s direction
. The speed remains unchanged, only the direction of velocity. The perpendicular (or normal) acceleration changes the trajectory, and that is all. That trajectory, however, can be circular, elliptic, or anything else.
