Force on a Current Carrying Conductor in a Magnetic Field

Q.

How are current and magnetic field related?

Q.

If the current flowing in the current-carrying conductor placed in a magnetic field is increased, the magnitude of force will

Q.

Magnetic field lines around a current-carrying straight conductor are concentric circles.

1. True
2. False

Q.

When a wire loop is rotated in a magnetic field, the direction of induced emf change by?

Q. A charged particle is moving at a certain speed perpendicular to a magnetic field. What would be the shape of the path of the particle in the field?

1. Linear
2. Circular
3. Elliptical
4. Irregular

Q.

A uniform magnetic field exists in the plane of a paper pointing from left to right as shown in Figure. The electron and the proton in the field experiences a force:

1. pointing into the plane of paper.

2. pointing out of the plane of the paper.

3. pointing opposite and along the direction of the uniform magnetic field on proton and electron respectively.

4. pointing into the plane of paper and out of the plane of paper for proton and electron respectively.
