Question
A toroid is a solenoid in the shape of a donut. The magnetic field inside the toroid is B=μ0NI/(2πR).
Suppose that a toroidal electromagnet with 146 loops uses a coil 1.2 m in diameter made from square copper wire. The power supply produces 120 V at a maximum power output of 4.0 kW.
If P=IV, what is the magnetic field strength inside the coil?
