Question

A long straight wire carries a convetional current of9 A to the left. A 50cm section of this wire is placed in amagnetic field (B=600mT) at aright angle to the field lines, where B comesout of your paper. Calculate the magnitude and the direction of themagnetic force FB acting on thesection of wire:                             Utilize vector cross-product- A long straight wire carries a convetional current of9 A to the left.

Explanation / Answer

Given that the current in the wire is I = 9 A Length of conductor is L = 50 cm = 0.5 m magnitude of magnetic field is B = 600 mT = 0.600T   angle between the current and the magnetic field is =90o --------------------------------------------------------------- Then the force on the wire is F = BIL sin                                                = BIL                                               = 2.7 N (upwards) From the right hand rule direction of force is upwards
