Solenoid (Electromagnetic) Force Calculator

What is a solenoid?

A solenoid is a long loop of wire wrapped along with a metallic core, which produces a uniform magnetic field when an electric current is passed. It uses the magnetic field created by an electric current to create linear motion.

What is electromagnetic force?

The electromagnetic force is a fundamental force of nature and this force is carried by electromagnetic fields. It is composed of magnetic fields and electric filed and causes electromagnetic radiation.

The electromagnetic force in a solenoid can be calculated using the electromagnet calculator above.

Solenoid electromagnetic force formula

The formula of electromagnetic force in a solenoid can be carved as:

F = (N × I)²μ₀ A / (2 g²)

Where,

F represents the force,

μ₀ is magnetic constant with the value of 4 × π × 10^-7,

N is the number of turns,

A refers to the area,

I refers to the current, and

g is the distance between the solenoid and a piece of metal.

The electromagnetic force calculator above uses the same formula to find the solenoid electromagnetic force.

How to find solenoid electromagnetic force?

Using the solenoid force calculator is the best and simplest way to calculate solenoid electromagnetic force. If you want to learn the manual process, follow the below steps.

• Identify and write down the values.
• Write down the solenoid force equation and place the values.
• Solve the equation for the value of

Example:

Find the electromagnetic force in a solenoid having 12 number of turns, 3 A current, with an area of 5 m² and distance of 2 m.

Solution:

Step 1: Write down the values.

N = 12

I = 3 A

A = 5 m

g = 2 m

μ₀ = 4 × π × 10^-7

Step 2: Use the solenoid electromagnetic force equation and place the values.

F = (N × I)²μ₀ A / (2 g²)

F = (12 × 3)² 4 × π × 10^-7× 5 / (2 × 2²)

F = (1296 × 4 × 3.1415 × 10^-7 × 5) / 8

F = 0.0010 N

The electromagnet strength calculator performs all of the above steps. The only difference is, it does it merely in a secondJ.
