In the sketch below, the two shaded regions have uniform magnetic fields directed out of the page. The magnitude of the field in the left region is B1 = 6.4 T, and the magnitude of the field in the right region is B2 = 0.5 T. Four identical square loops of wire are shown with arrows indicating their velocities. Each side of the loop has a length of L = 0.25 m. The value inside each arrow gives the magnitude of the velocity. The speeds are all multiples of v = 0.47 m/s. For the instant illustrated, find the magnitude and direction (clockwise or counterclockwise) of the induced emfs in each of the four wires: EA, EB, EC, and ED.

During a transcranial magnetic stimulation (TMS) treatment, a magnetic field, typically of magnitude 5.00 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 65.0 us . Assume that the magnetic field is uniform over a circular area of diameter 2.00 x 10-² m inside the brain. What is the magnitude of the average induced emf around this region of the brain during the treatment? average induced emf: V

In each of the figures below, a uniform magnetic field B points in the +x-direction. The magnitude of the field is 1.50 T. In each figure, a square loop, shown edge-on, with sides of length l = 0.255 m, is oriented within the magnetic field as shown. In the left figure, the loop is oriented vertically, perpendicular to the magnetic field. In the middle figure, it is tilted such that the plane of the loop makes a 60.0° angle with the magnetic field. In the right figure, the loop is oriented horizontally, parallel to the magnetic field. y 60.0° What is the magnetic flux (in Wb) through the loop in each of the three cases shown? (a) perpendicular to the magnetic field Wb (b) 60.0° from the magnetic field Wb (c) parallel to the magnetic field Wb

In each of the figures below, a uniform magnetic field B points in the +x-direction. The magnitude of the field is 3.00 T. In each figure, a square loop, shown edge-on, with sides of length { = 0.380 m, is oriented within the magnetic field as shown. In the left figure, the loop is oriented vertically, perpendicular to the magnetic field. In the middle figure, it is tilted such that the plane of the loop makes a 60.0° angle with the magnetic field. In the right figure, the loop is oriented horizontally, parallel to the magnetic field. 60.0 What is the magnetic flux (in Wb) through the loop in each of the three cases shown?

Please answer carefully.

Three long, parallel conductors each carry a current of I = 2.40 A. The figure below is an end view of the conductors, with each current coming out of the page. Taking a = 1.20 cm, determine the magnitude and direction of the magnetic field at the following points.   (a) point A magnitude  µT direction          (b) point B magnitude  µT direction          (c) point C magnitude  µT direction

A five-sided object, whose dimensions are shown in the drawing, is placed in a uniform magnetic field. The magnetic field has a magnitude of 0.30 T and points along the positive y direction. Determine the magnetic flux through each of the five sides.

I am working on physics homework and am stuck on this one! Help would be great, thank you!
