2. There are three wires carrying current. The direction of the currents for Wires 1 & 2 are as shown in the drawing to the right. The current in Wire 1, 11, is smaller than the current in Wire 2 (11 <12). At Point X, which is equidistant from all three wires, the magnetic field is zero. Wire 1 Wire 2 Wire 3 A) Determine the direction of the current in Wire 3 (13). Explain B) If Ti = 2A...
The size of the magnetic force on a straight wire of length L carrying current I in a uniform magnetic field with strength B is F=ILBsin(?). Here ? is the angle between the direction of the current (along the wire) and the direction of the magnetic field. Hence Bsin(?) refers to the component of the magnetic field that is perpendicular to the wire, B?. Thus this equation can also be written as F=ILB?. The direction of the magnetic force on...
