Question

How is a current carrying wire placed in a magnetic field so that magnetic field does not act on it? Select the proper choice from the given multipule choices.
(A) Parallel to magnetic field
(B) Perpendiculr to magnetic field.
(C) At an angle 40° with magnetic field
(D) Can be arranged any way.

Answer 1

Answer:

parallel to magnetic field...........

Answer 2

A current carrying wire is placed (A) Parallel to magnetic field so that magnetic field does not act on it.

Explanation:

When the current carrying wire is placed in a magnetic field, then the wire is subjected to magnetic force.

The magnetic force depends on the following factors

• Current amount
• Magnetic field strength
• Length of the wire in magnetic field
• Angle between wire and magnetic field

So, when the angle between wire and magnetic field is 0° or 180°, then the magnetic force is zero. When the angle between wire and magnetic field is 90°, then the magnetic field is maximum.
