# Solenoid Coil - Current carrying coil

Solenoid is a long loop of wire wrapped along metallic core, which produces a uniform magnetic field when electric current is passed. Electromagnetic force is a fundamental force of nature and this force is described by electromagnetic fields, this online calculator can be used to calculate solenoid electromagnetic force by filling in requested fields.

## Solenoid Coil

### To calculate Solenoid Coil Electromagnetic Force:

• Current (i)

amps

• Area (a)

m2

• Number of turns (n)

turns

• Length (g)

m

•

• F

Newtons

Formula:

F = (n x i)2 x magnetic constant x a / (2 x g2)

Where,
F = Force, i = Current, g = Length of the gap between the solenoid and a piece of metal, a = Area n = Number of turns, Magnetic constant = 4 x PI x 10-7.
