The lower end of the thin uniform rod in (Figure 1) is attached to the floor by a frictionless hinge at point P. The rod has mass 0.0940 kg and length 18.0 cm and is in a uniform magnetic field 0.130 T that is directed into the page. The rod is held at an angle 58.0∘ above the horizontal by a horizontal string that connects the top of the rod to the wall. The rod carries a current 12.0 A in the direction toward P. Figure 1 of 1 Part A Calculate the tension in the string. Use the fact that τ = 12 IBL2 for a uniform bar of length L carring a current I in a magnetic field B. Express your answer with the appropriate units.

The circuit shown in the figure is used to make a magnetic balance to weigh objects. The mass m to be measured is hung from the center of the bar, that is in a uniform magnetic field of 1.50 T, directed into the plane of the figure. The battery voltage can be adjusted to vary the current in the circuit. The horizontal bar is 60.0 cm long and is made of extremely light-weight material. It is connected to the battery by thin vertical wires that can support no appreciable tension; all the weight of the suspended mass m is supported by the magnetic force on the bar. A resistor with R = 5.00 Ω is in series with the bar; the resistance of the rest of the circuit is much less than this.

A 0.300−m-long bar moves on parallel rails that are connected through a 5.60 Ω resistor, as shown in (Figure 1), so the apparatus makes a complete circuit. You can ignore the resistance of the bar and rails. The circuit is in a uniform magnetic field 1.60 T that is directed into the plane of the figure. Figure 1 of 1 Part A At an instant when the induced current in the circuit is counterclockwise and equal to 1.90 A, what is the magnitude of the velocity of the bar?
