You have designed and constructed a solenoid to produce a magnetic field equal in magnitude to that of the Earth (5.0  10-5 T). If your solenoid has 500 turns and is 29 cm long, determine the current you must use in order to obtain a magnetic field of the desired magnitude

A square coil of wire carries a current of 3.11 A. The coil has 340 turns and has a side length of 0.71 m. If the coil is placed in a magnetic field and the maximum torque the field can apply to the coil is 1.23E+03 N*m, what is the strength of the magnetic field? (Answer in T).

A magnetic field has a magnitude of 0.0527 T and is uniform over a circular surface whose radius is 0.226 m. The field is oriented at an angle of 27.9o with respect to the normal to the surface. What is the magnetic flux through the surface?

An air-core solenoid with 64 turns is 8.00 cm long and has a diameter of 1.20 cm. When the solenoid carries a current of 0.710 A, how much energy is stored in its magnetic field?

During a transcranial magnetic stimulation (TMS) treatment, a magnetic field, typically of magnitude 5.00 T, is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 65.0 us . Assume that the magnetic field is uniform over a circular area of diameter 2.00 x 10-² m inside the brain. What is the magnitude of the average induced emf around this region of the brain during the treatment? average induced emf: V

The MIT Francis Bitter Magnetic Laboratory has achieved a magnetic field of 37.2 T(as of 2004). Find the current necessary to produce such a field near the center of asolenoid with radius 2.40 cm, length 32.0 cm, and 4.00 · 104 turns

A 2278 turn solenoid is carrying a current of 18.2 A. The solenoid is 98.45 cm long. What is the magnitude of the magnetic field (in milli-tesla) through the center of the solenoid?
