Question Description:

20.50

A copper wire is 7.00 m long and has a cross-sectional area of 1.00 10-4 m2. This wire forms a one turn loop in the shape of a square and is then connected to a battery that applies a potential difference of 0.200 V. If the loop is placed in a uniform magnetic field of magnitude 0.200 T, what is the maximum torque that can act on it? The resistivity of copper is 1.7 multiplied by 10-8 ยท m.

Answer

20.50
