Asolenoid 0.425 m long has 950 turns of wire. what is the magnetic field in the center of the solenoid when it carries a current of 2.75 a? (jc 19.57)

The magnetic field in the center of the solenoid is .

Explanation:

Given that,

Length of solenoid = 0.425 m

Number of turns N = 950

Current I = 2.75 A

The magnetic field in the center of the solenoid is the product of the current , number of turns per unit length and permeability.

In mathematical form,

Where,

N = number of turns

L = length

I = current

Now, The magnetic field

Put the value into the formula

Hence, The magnetic field in the center of the solenoid is .

pretty sure it's false

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
