When seen from the end, three long, parallel wires form an equilateral triangle 6.0 cm on a side. The wires each carry a 2.0 A current, with one current direction opposite the other two. Y Part A What is the magnetic field strength at the center of the triangle? Express your answer with the appropriate units.

A 0.55-meter-long wire carries a current with electron flow directed to the East. It is present in a magnetic field of intensity of 0.050 T and directed to the South. The force acting on the wire is 0.220 N. a. What is the magnitude of the current in the wire? b. In what direction is the force acting on the wire?

A long, cylindrical conductor of radius  has two cylindrical cavities each of diameter  through its entire length. A current  is directed out of the page and is uniform through a cross section of the conducting material. Find the magnitude and direction of the magnetic field in terms of  and  at .point  P1 .point P2

The uniform 30.0 mT magnetic field in the figure points in the positive z-direction. An electron enters the region of magnetic field with a speed of 5.50 x 106 m/s and at an angle of 30° above the xy-plane.
