A closely wound coil has: radius of 5cm, 200 turns, and Resistance of 10 ohms. There is a 10.0mA of constant current in the search coil. The magnetic field through the coil is 0 at t=0, perpendicular to the area of the coil. The coil is completely inside a uniform magnetic field.

(a) Find the magnitude of the magnetic field at t=20.0ms.

(b)The magnetic field from part (a) is produced by a larger coil which is outside of the first coil. The outer coil has: 800turns, r=30cm.

Find the current through the outer coil at t=20.0ms.

(c)The inner coil rotates, forming an angle of 60 degree with the outer coil.

Find the current through the inner coil.

A solenoid (coil) of radius R has 10 turns per centimeter. It is 10cm long, and the coiled wire carries a current I. In addition to the coil of wire, a second wire runs right down the central axis of the solenoid, carrying a current of 2I. (The solenoid wire doesn't intersect this second wire, because the former wraps around the latter, always a distance R away.) A) Find the magnitude of the total magnetic field at a distance R/2...

A circular coil of 300 turns and radius 10 cm is connected to a current integrator. The total resistance of the circuit is 45 Ω. The plane of the coil is originally aligned perpendicular to the earth’s magnetic field at some point. When the coil is rotated through 90◦ , the charge that passes through the current integrator is measured to be 9.2 µC. Calculate the magnitude of the earth’s magnetic field at that point. Answer in units of µT
