Question

Study the diagram alongside carefully and answer the following question:

Due to two magnetic fields, i.e., the permanent magnet and the magnetic field set up by the conductor, the force experienced by the conductor depends upon:

पर्याय

• Strength of current flowing through conductor

• Magnetic intensity of permanent magnet

• Length of conductor within the pole pieces of permanent magnet

• all of these

Answer 1

All of these

Explanation:

The force on a current-carrying conductor placed in a magnetic field is given by F = BIL, where I is the current, B is the magnetic field intensity and L is the length of the conductor inside the field. So the force depends on three factors: the current, the magnetic field intensity of the permanent magnet, and the length of the conductor within the pole pieces.
