4. The conducting rod in the diagram below is 15 cm long and is moving at a speed of 0.95 m/s perpendicular to
the magnetic field.
lfthe resistance in the circuit is 1.5 ohms and a current of 5.6x10.. A is induced in the circuit
a) What is the magnitude of the magnetic field?
1)) What is the direction of the induced current?
e conducting rod in the diagram below is 30.0 cm long and is moved perpendicular to 0.950 T magnetic
f .
If the resistance in the circuit is 3.25 ohms what force is required to move the rod at a constan 0 m/s?
6. A plane with a wing-span Of6.25 m is flying horizontally at a speed of95.0 m/s ifthe vertical component
ofthe Earth's magnetic field is 4.70x10... T what is the induced emf between the tips of the wings?
7. The conducting rod in the diagram bel IW is 30 ' cm ong and is moving at a speed of 3.00 m/s perpendicular
