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 10-turn coil of wire having a diameter of 1.0 cm and a resistance of 0.90 Ω is in a 1.0 mT magnetic field, with the coil oriented for maximum flux. The coil is connected to an uncharged 2.0 μF capacitor rather than to a current meter. The coil is quickly pulled out of the magnetic field. Afterward, what is the voltage across the capacitor? Hint: Use I =dq/dt to relate the net change of flux to the amount of...
