Enter the current, number of turns, area, and gap length into the calculator to determine the solenoid force.

Solenoid Force Formula

The following formula is used to calculate the force produced by a solenoid.

F= (n*I)^2 * c * A / ( 2 * d^2) 
  • Where F is the force (newtons)
  • n is the number of turns
  • I is the current (amps)
  • c is a constant (12.566*10^-7)
  • A is the area (m^2)
  • D is the distance between the solenoid and the metal

To calculate the solenoid force, square the product of the number of turns and the current, multiply the result by the constant and area, then divide by 2 times the distance squared.

Solenoid Force Definition

A solenoid force is defined as the total force produced by any given solenoid. Solenoids are coils or wires that produce a magnetic field when electricity is run through them.

Solenoid Force Example

How to calculate solenoid force?

  1. First, determine the number of turns.

    Calculate or measure the total number of turns of the solenoid.

  2. Next, determine the current.

    Measure the current running through the solenoid.

  3. Next, determine the area.

    Measure the area of the metal the magnetic field is acting on.

  4. Next, determine the distance between the solenoid and metal.

    Measure the distance to the metal plate from the center of the solenoid.

  5. Finally, calculate the solenoid force.

    Calculate the solenoid force using the equation above.

FAQ

What factors affect the force produced by a solenoid?

The force produced by a solenoid is affected by several factors including the number of turns in the coil, the intensity of the current flowing through the coil, the area of the coil, the distance between the solenoid and the metal object, and the magnetic properties of the core material.

Can the direction of the solenoid force be changed?

Yes, the direction of the solenoid force can be changed by reversing the direction of the current flowing through the solenoid. This reverses the polarity of the magnetic field, thus changing the direction of the force.

How can the strength of a solenoid be increased?

The strength of a solenoid can be increased by increasing the number of turns in the coil, increasing the current flowing through the coil, using a material with higher magnetic permeability for the core, or decreasing the gap between the solenoid and the metal object it is acting upon.
