Short Answer

A 40-turn, 4.0-cm-diameter coil with surrounds a 3.0-cm-diameter solenoid. The solenoid is 20 cm long and has 200 turns. The

60 current through the solenoid is I = . What is if the maximum induced current in the coil is ?

The Induced current

See the step by step solution

Step by Step Solution

Step 1: Solenoid

Relationship between the applied magnetic flux, the grommet initiates a current. The torsion that a rotor emits was given by,

The current, .

Solenoid Area,

Faraday's Law,

Step 2: Ohm's law

The angle , the induced emf

The Ohm's law calculation we using the induced current through the coil

Step 3: Plug the values

we plug the values for
