A uniform magnetic field is directed in the -z direction.
A uniform magnetic field is directed in the -z direction. A rectangular wire wound 8 times with a length of 0.7 meters and width of 0.7 meters is placed in the x-y plane in the field. The magnetic field is changed in magnitude from 15 Tesla to 4 Tesla in a time of 0.6 seconds.If the resistance of the wire is 8 Ohms, what is the magnitude and direction of its magnetic moment produced by the average induced current in A m2? Indicate negative z direction by including a negative sign and don't include a sign for the positive z direction.
