As shown in the figure, a conducting rod with a
linear mass density of 0.0380 kg/m is
suspended by two flexible wires of negligible mass in a uniform
magnetic field directed out of the page. A
power supply is used to send a current through the rod such that
the tension in the support wires is zero.

A long, straight wire with linear mass density of 50g/m is
suspended by threads, as shown in the figure . There is a uniform
magnetic field pointing vertically downward. A 13A current in the
wire experiences a horizontal magnetic force that deflects it to an
equilibrium angle of 10 degrees. What is the strength of the
magnetic field B?

3.1. Two metallic rods of length L = 40 cm and unknown linear mass density A are suspended from a support using lightweight strings of length s = 8 cm, as shown in the diagram (a) below. The rods are then connected to a circuit in such a way that same current I = 20 A passes through both rods, but flows in opposite directions. When connected in such a way, the rods move away from each other and at...
