For a particular scientific experiment, it is important to becompletely isolated from any magnetic field, including the earth'sfield. A 1.20 -diameter current loop with 200 turns of wire is setup so that the field at the center is exactly equal to the earth'sfield in magnitude but opposite in direction.

What is the current in the current loop?

For a particular scientific experiment, it is important to be completely isolated from any magnetic field, including the earth's field. The earth's field is approximately 50 uT, but at any particular location, it may be a bit more or less than this. A 1.00-m-diameter current loop with 200 turns of wire is adjusted to carry a current of 0.215 A; the coil's field at the center is exactly equal to the earth's field in magnitude but opposite in direction so that the total field at the center of the coil is zero. What is the strength of the earth's magnetic field at this location?

Induced EMF and Current in a Shrinking Loop.

A circular loop of flexible iron wire has an initial circumference of 161 cm , but its circumference is decreasing at a constant rate of 13.0 cm/s due to a tangential pull on the wire. The loop is in a constant uniform magnetic field of magnitude 1.00 T , which is oriented perpendicular to the plane of the loop. Assume that you are facing the loop and that the magnetic field points into the loop. Find the magnitude of the emf EMF induced in the loop after exactly time 8.00 s has passed since the circumference of the loop started to decrease.

A uniform magnetic field B is perpendicular to the plane of a circular loop of diameter 10 cm formed from wire of diameter 2.5 mm and resistivity 1.69 x 10^-8 Om. At what rate must the magnitude of B change to induce a 10 A current in the loop?
