A current loop is in the magnetic field as shown. Which way will this current loop rotate? the loop will not rotate clockwise counterclockwise B

The diagram below shows two concentric, conducting, circular loops with currents traveling in opposite directions. If the current in the outer loop is I2  = 90.0 μA, what must be the magnitude of the current in the inner loop so that the total magnetic field at the center, C, of both loops is zero? a. 60.0 μA   b. 45.0 μA   c. 90.0 μA   d. 75.0 μA   e. 105 μA

A cylindrical solenoid that is 40-cm long generates a uniform magnetic field of strength 1.4 T inside the solenoid when the current is 7.0 A. How many turns of a single coil are present in this solenoid?    a. 40,000 turns   b. 64,000 turns   c. 56,000 turns   d. 48,000 turns   e. 32,000 turns

The copper sheet shown below is partially in a magnetic field. What happens when it is pulled to the right (select all that apply)? O The copper sheet feels an opposing force to the left Copper is a nonmagnetic material, so it is unaffected by the magnetic field The copper sheet feels a net torque in the direction parallel to its direction of motion A clockwise electric current flows in the copper sheet

Figure shows four particles moving to the right as they enter a region of uniform magnetic field, directly into the page. All particles move at the same speed and have the same charge.  Which particle has the least mass?

What is the direction of the magnetic field at point P?
