1. State an equation for the magnetic force, Fmag, exerted on a conductor of length l, carrying a current I, at an angle θ, to a magnetic field of strength B.
2. A conductor of length 5 cm carries a current of 250 mA and sits perpendicularly in a magnetic field of strength 4.0×10−5 T.
Calculate the force experienced by the conductor.
The wire is moved slightly so the direction of the current makes an angle of 30∘ to the magnetic field. Calculate the force experienced by the wire.
