During transcranial magnetic stimulation (TMS) treatment, a magnetic field typically of magnitude 0.50 T is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 93 us. Assume that the magnetic field is uniform over a circular area of diameter 2.0 cm inside the brain. 1) What is the magnitude of the average induced emf around this area in...
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 4T, 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 0.191 A ; at this current, the coil's field at the center is exactly equal to the earth's field in magnitude but...

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 ?T,
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 0.219A ; at this current, the coil's
field at the center is exactly equal to the earth's field in
magnitude...
A 9.0-cm -long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wire and rail is 0.34 Ω . Pulling the wire with a force of 1.0 N causes 3.5 W of power to be dissipated in the circuit. What is the speed of the wire when pulled with 1.0 N ? Express your answer in meters per second.

How does the magnitude of magnetic field around a long straught current carrying wire of radius R depend on radial distance r R from the long anis OF wire ? Assuming that the current is steady and uniformly distrbule within v the wire, How does, the field magnitude depera on the radial distance rar from the wire axis
1. Magnetic Field Generated by a Current in a Wire Under steady-state conditions, a magnetic field B has curlB in a region where there is no current. We study the steady-state magnetic field B due to a constant current in an infinitely long straight thin wire. The magnitude of the magnetic field at a point depends only on the distance from the wire and its direction is tangent to the circle around the wire and determined by the right-hand rule....
