A packed bundle of 100 long, straight, insulated wires forms a cylinder of radius R = 0.500 cm. If each wire carries 2.00 A, what are (a) the magnitude and (b) the direction of the magnetic force per unit length acting on a wire located 0.200 cm from the center of the bundle? (c) What If? Would a wire on the outer edge of the bundle experience a force greater or smaller than the value calculated in parts (a) and (b)? Give a qualitative argument for your answer.
five long parallel wires in an xy plane are separated by distance d = 8.00 cm, have lengths of 10.0 m, and carry identical currents of 3.00 A out of the page. Each wire experiences a magnetic force due to the currents in the other wires. In unit-vector notation, what is the net magnetic force on (a) wire 1, (b) wire 2, (c) wire 3, (d) wire 4, and (e) wire 5?
TRUE OR FALSE
(a) Given the formula, F=qv⃗ ×B⃗ =qvBsinθF=qv→×B→=qvBsinθ, the magnetic force on a moving charged particle is always perpendicular to the magnetic field. It therefore follows that the trajectory of a moving charge is also always perpendicular to the magnetic field lines.
(b) The magnetic force acting on a charged particle can never do work because at every instant the force is perpendicular to the velocity.
