Find the magnetic field at the center of the solenoid

Reference no: EM13274776

1) Solenoids produce magnetic fields that are relatively intense for the amount of current they carry. To make a direct comparison, consider a solenoid with 55 turns per centimeter, a radius of 1.89 cm, and a current of 0.190 A.

(a) Find the magnetic field at the center of the solenoid.

(b) What current must a long, straight wire carry to have the same magnetic field as that found in part (a)?

Let the distance from the wire be the same as the radius of the solenoid, 1.89 cm.

2) A 12.1-ÂµC particle with a mass of 2.80 ? 10?5 kg moves perpendicular to a 1.01-T magnetic field in a circular path of radius 29.8 m.

(a) How fast is the particle moving?

(b) How long will it take the particle to complete one orbit?

3) An electron moves at right angles to a magnetic field of 0.13 T. What is its speed if the force exerted on it is 8.6 multiply.gif 10-15 N?
