Question

A wire coil has 1340 turns of copper wire. The cross-section radius is .4 mm. It has a diameter of 3.4 cm and a length 8.95 cm. It is oriented along the y-axis. Each end is connected to a 12 V battery.   The temp. is 210C.

a)find the length of the wire needed for the coil
b)the resistance of the coil
c) the magnitude of the magnetic field at a point within the coil
d) a +30 uC particle is initialally at a point within the coil at a velocity of .30 m/s in the +y direction. give the magnitude of the force on the particle.
e)a -5 uC particle is initialally at a point within the coil at a velocity of 4 m/s in the +x direction. give the magnitude of the force on the particle

Answer 1

n = number of turns per meter length of the solenoid
