If there is a current of 2 A flowing counterclockwise in the coil (as seen from the +z direction) what is the magnitude of the torque on the loop due to the above magnetic field? Enter a description of your calculations and your final answer in the text box (just as if it were a HW assignment)

A long solenoid that has 870 turns uniformly distributed over a length of 0.420 m produces a magnetic field of magnitude 1.00 x 10-4 T at its center. What current is required in the windings for that to occur? mA Need Help? Read It Master It

Also explain what is magneto motive force???

You have a solenoid with an into all current of 577A and a turn dentistry of 6601 loops/m What is the intial magnetic field through the solenoid ? the current in the solenoid drops to 34 A over the course of 4ms. What is the final magetic field through the solenoid ? the coil has a resistance of 20. What is the current though the coil? what is the power disssipated by the coil? inside the solenoid 56loops and a radius of 6.2cm. What is the magnitude of the induced in the 56 turn coil. Positive nunber

Please solve thiss questionnnnn

The magnetic circuit shown below has mean magnetic path of 0.5 m, a relative permeability of 1000, and a uniform cross sectional area equal to 5×104 m². The coil has 120 turns and, when connected to a 120 v, 60 Hz voltage source, draws 5 A. Determine the inductance of the coil in Henry. Give your answers correct to 3 decimal places. Answer:

The maximum amount of voltage is induced time(s) in 3600 of mechanical rotation for a single loop coil rotating between a north and south magnetic poles of a DC generator. a) one b) two c) four d) none of the above

In a moving coil instrument, the coil has a length of 5 cm, a width of 4 cm and 80 turns. The magnetic flux, density in the air gap is 0.1 Wb/m², the hair spring provides a controlling torque of 0.5 × 10² Nm/ degree deflection of the coil. What current will be required to give a deflection of 600?

Coiling a current-carrying wire: Select one: distributes the magnetic poles over the whole coil. creates inductance. multiplies the magnetic force around each turn of wire. sets up field lines at right angles to the coil axis.
