circular loop of radius 4.50 cm that carries a current of 15.0 A.
Calculate the magnetic field B at the center of the loop. Consider
the coordinate system in the figure. If the circular loop lies in
the xy plane and if the current flows clockwise around the loop,
which direction does the magnetic field point inside the...
a) a horizontal long straight wire carries a current of I1= 8A from left to right. The wire is tangential to a circular loop of wire of Radius R= .03 m lying immediately below it. The loop carries a current of l2= 2A in the counter clockwise direction. Assuming that the thickness of the wires are negligible, find the magnitude and direction of the net magnetic field at the center of the circular loop b) a second long wire also...
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).
