What is the force felt by the electrons and the nuclei in the rod when the external field described in the problem introduction is applied? (ignore internal fields in the rod for the moment.)

"The nuclei experience a force to the right and the electrons experience a force to the left"

Explanation:

The oppositely charged particles will start attracting each other, on the other hand the like particles will start repelling one another. Electrons are placed in such a manner in the orbit which is near the nucleus by the electromagnetic force, and hence the nucleus present in the center of the atom is positively charged and are attracted towards the negatively charged atoms. The electric and magnetic force helps electrons to hold on the atoms.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
