Polo Sport Jumper Vintage, If the current is steady, then the magnetic flux through the loop will remain constant. A coil consisting of 10 turns of wire each in an area of 0.025 m^2 is rotating in a magnetic field that is decreasing at the rate of 0.32 T/s. An electromagnet produces a 10 mT magnetic field. Centripetal acceleration (ac) = 88.2 m/s2 (i), we get= 2.97x 10-4T After 15s the normal to the coil is 60 with the magnetic field. The current in both wires is I = 5.00 A in the negative y direction. The average induced emf is -0.058V. An infinite sheet of current lying in the yz plane carries a surface current of linear density Js. Prow that the magnetic field near the sheet is parallel to the sheet and perpendicular to the current direction, with magnitude 0Js/2.
