Question

IV) Force on a current carrying wire in the presence of a B-field Consider a wire carrying a current I. The magnetic force experienced by the current carrying wire of length L in the presence of a B-field can be written as: where 0is the angle between the current direction and the B-field direction. This apparatus consist of a pole magnet with north-south pole facing one another and oriented vertically. A wire that is free to swing between the poles is connected across the terminals of a voltage regulated current limited power supply A) The power supply should be switched off. 1) The voltage adjust knobs turned all the down (counter clockwise) and 2) The current adjust knobs all the way down (counter clockwise) B) Switch on the power supply. 3) Turn the voltage adjust knobs all the upp (clockwise) and 4) Carefully turn up the current adjust (clockwise),

Explanation / Answer

This is the description of the experiment to test the force on a current carrying wire due to a magnetic field. However what is the question asked is not mentioned here.
