At a particular point on Earth, the magnitude of the Earth's magnetic field is 3.50 x 10-5 T. At this point, the field through a small square loop is essentially uniform. The area of the loop is 30.0 cm2. What is the magnitude of the magnetic flux (in T: m2) through the loop when the loop is at the following orientations? (a) the magnetic field is perpendicular to the plane of the loop 1.05*10**-3 X T. m2 (b) the magnetic field and the normal to the plane of the loop are at a 20.0° angle 6.68*10**-8 T.m2 (c) the magnetic field and the normal to the plane of the loop are at a 90.0° angle T.m?

An electron enters a region of space containing a uniform 2.89 × 10-³ T magnetic field. Its speed is 163 m/s and it enters perpendicularly to the field. Under these conditions, the electron undergoes circular motion. Find the radius r of the electron's path and the frequency f of the motion. r = m %3D Hz

Two long wires are oriented so that they are perpendicular to each other. At their closest, they are 20.0 cmcm apart (Figure 1).   What is the magnitude of the magnetic field at a point midway between them if the top one carries a current of 22.0 AA and the bottom one carries 13.5 AA ?
