1 a coil made of 5 loops of wire with a radius of 100 cm, Ask an Expert

Academics

1) A coil made of 5 loops of wire with a radius of 10.0 cm rotates about its diameter in a uniform magnetic field of 1.60 T. To produce a maximum of 5.00 V, what speed should it rotate at (in unit of rad/s)? If you use the unit of revolutions per second, what should be the rotation frequency?

2) Two long straight wires are parallel and carry current in opposite directions. The currents are 8.00 and 12.0 A and the wires are separated by 4.00 cm. What is the magnetic field in Tesla at a point midway between the wires?
