Question 12

A straight current-carrying conductor is placed perpendicular to a uniform magnetic field, experiencing a magnetic force. Three proposed changes to increase this magnetic force are:

  1. Increase the current in the conductor.
  2. Increase the strength of the magnetic field.
  3. Rotate the conductor so that it lies parallel to the magnetic field.

Which of these suggestions are correct?

A

1 and 2 only

B

1 and 3 only

C

2 and 3 only

D

1, 2 and 3
