A moveable (massless and frictionless) bar with a length of L = 11/50 m is being moved at a constant velocity of 62/10 m/s from left to right along two conducting rails by an external force, F, as shown in the Figure. If the system is immersed in a uniform magnetic field (out of the paper) with magnitude 11/100 Tesla, What is the induced current and its direction of the loop if the resistance is 11/5 Ω ?

A loop of highly conducting wire is placed in a magnetic field that is increasing out of the page (through the loop) at a rate of 1.80 T/s. If the loop has an area of 0.400m^2, calculate the current flowing in Amps through the 5.00 ohm resistor.

A loop is fixed in position in the location of a magnetic field directed out of the page.  The magnetic field gets weaker over time. Determine the direction of the induced current in the wire.

In the arrangement shown in the figure, 3.51 A current flows in the same direction from the coils with 320 windings and a radius of 7.50 cm. In this case, when we place the hall probe at a point 3.00 cm from the center of the coils, a deviation of 39 μA is observed in the microammeter connected to the hall probe. Since the microammeter deviates by 51.2 μA when we hold the Hall probe at a distance of 3.00 cm from a bar magnet, calculate the magnetic field of the bar magnet at this distance. (μ0 = 4π x 10-7 T.m/A, π = 3.14)

Consider A rod of length 40 cm moving with a velocity of 30 m/s to the left in a magnetic field of 0.2 T into the page. The loop has a small resistance of 2 ohms. Find a) the emf in the loop b) the magnitude and direction of induced current c) the magnetic force acting on the rod and its direction
