A 60 cm long wire is bent into a circle. The circle of wire is placed flat on a table and a uniform magnetic field is applied to the whole table which points upwards. The magnetic field has strength which varies with time t as B=0.025 t^2 T/s^2. The wire has a resistance of 45 ohms. what is the current induced in the circuit at t= 1.5s? In which direction does it flow?

A square wire wrapped 24 times with a length of 0.2 meters is placed in the x-y plane in a uniform magnetic field directed in the -z direction. The magnetic field changes in magnitude from 0.14 T to 0.38 T in a time of 0.3 seconds. What is the amount, in amps, and the direction of the average induced current if the resistance of the wire is 0.8 Ohms? Indicate clockwise by including a negative sign and counter-clockwise by not...
