A train is moving directly south with a speed of 10 m/s. if the downward vertical component of the Earth’s magnetic field is 0.54 G, compute the magnitude and direction of the emf induced in a rail car axle 1.2 m long

A single loop of copper wire, lying flat in a plane, has an area of 9.00 cm2 and a resistance of 2.10 Ω. A uniform magnetic field points perpendicular to the plane of the loop. The field initially has a magnitude of 0.500 T, and the magnitude increases linearly to 3.00 T in a time of 1.06 s. What is the induced current (in mA) in the loop of wire over this time?

1. A 27.4-meter-long spacecraft flies past a neutron star, and passes through the neutron star s extremely powerful magnetic field of strength 8.88 x 10^4 T. The spacecraft travels at a velocity of 5.67 km/s in a direction perpendicular to the magnetic field; the spacecraft s long axis is also perpendicular to the magnetic field. What is the induced emf (voltage) between the two ends of the spacecraft?     1.38E+09 V   1.38E+10 V   1.38E+07 V   1.38E+06 V

A pickup truck has a width of 79.9 in. If it is traveling north at 36 m/s through a magnetic field with vertical component of 37 µT, what magnitude emf is induced between the driver and passenger sides of the truck? mV Need Help? Read It

As a diligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.15 m long rod as you jog at 3.17 m/s, holding the rod perpendicular to your direction of motion. What is the magnitude B of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.287 mV across the rod? Express the answer in milliteslas. B = mT

y Here, a long solenoid of 20000 turns/meter and r=2 cm is oriented along the z-axis (outer circle). There is a small coil of 10 loops of wire of radius 1 cm concentric with the solenoid and lying in the x-y plane (inner circle). An alternating current of magnitude 10 A switches direction every 0.001 seconds in the solenoid. What is the magnitude of the EMF generated in the small loop, in Volts? Answer:

A 24-turn circular coil of wire has diameter 1.09 m. It is placed with its axis along the direction of the Earth's magnetic field of 47.0 µT and then in 0.200 s is flipped 180°. An average emf of what magnitude is generated in the coil? x What is the change in the magnetic flux during this time interval? mV

The device shown in the figure allows you to measure the rate of blood flow in the vessels of the human body, since the blood contains electrically charged ions. Suppose that the blood vessel measures 2.0 mm in diameter, that the magnetic field is 0.080 T and that the fem measurement is 0.10 mV. Is this statement True or False? N S Voltímetro
