A square wire wrapped 24 times with a length of 0.2 meters is placed in the x-y plane in a uniform magnetic field directed in the -z direction. The magnetic field changes in magnitude from 0.14 T to 0.38 T in a time of 0.3 seconds. What is the amount, in amps, and the direction of the average induced current if the resistance of the wire is 0.8 Ohms? Indicate clockwise by including a negative sign and counter-clockwise by not...

3) A square wire with current in it, wrapped once, is placed in the x-y plane. It's sides have a length of 1.8 m and the magnetic moment produced by it is 6 A m2 in the +z direction. The square wire is then reshaped, using all the wire from the square, into a circle with the same current as the square. The circle is then placed into the x-y plane (first quadrant) such that it's magnetic moment is also...

If the resistance of the wire is 7 Ohms, what is the magnitude and direction of its magnetic moment produced by the average induced current in A m2
A uniform magnetic field is directed in the -z direction. A rectangular wire wound 5 times with a length of 0.7 meters and width of 0.8 meters is placed in the x-y plane in the field. The magnetic field is changed in magnitude from 15 Tesla to 4 Tesla in a time of 0.6 seconds. If the resistance of the wire is 7 Ohms, what is the magnitude and direction of its magnetic moment produced by the average induced current...

A Long wire runs along the x-axis with a current of 3.2A, with the current in the -x direction. A circular loop of wire is placed directly on top of the wire with the loop in the x-y plane. This loops has a radius of 0.30 m with a counter-clockwise current of 0.67 A. Calculate the net magnetic field at a distance 0.21 m directly above the center of the ring (calculate in vector form).

To make an electric motor, you create a circular loop of wire with radius 0.0100 m. You also have a magnet that can produce a relatively uniform magnetic field of strength 0.30 T 2. a. At a certain point, the magnetic flux through the loop is 2.00 x 10- T.m2; what is the angle between the plane of the loop and the field? (Note: the angle is zero if the loop is oriented like figure P27.21 in Practice, p. 495.)...

A circular loop of wire with area A lies in the y-plane. As viewed along the z axis looking in the -z direction toward the origin, a current I is circulating clockwise around the loop. The torque produced by an external magnetic field B is given by tau = D(4i - 4j), where D is a positive constant, and for this orientation of the loop the magnetic potential energy U = -mu middot B is negative. The magnitude of the...

1. Suppose that a thin wire is wrapped 25 times around a balloon, and then placed in a uniform magnetic field that has magnitude 1.3 T and points in a direction perpendicular to the coil of wire. If the balloon is inflated such that its radius increases by 1 cm per second, what will the potential difference generated in the coil be when the balloon has a radius of 5 cm? If the resistance in the coil is 25 Ohms,...
