Magnetic Force Between Two Wires

The force produced by charge motion is known as a magnetic force. Simply put, the magnetic force between two moving charges is the influence of a magnetic field formed by the other one of the charges.

The magnetic force between current-carrying wires is usually calculated using the cross product. The equation for the magnetic force between wires is F/L = μo x Ia x Ib /(2πd)

  • Where, Ia, Ib = current flowing in the first and second wires
  • d = distance between the wires
  • F/L = force per unit length
  • μo = permeability of free space that has a constant value. μo = 4π x 10^-7 Tm/A

If two wires come into contact with each other, attraction and repulsion will occur. When two wires transmit current in the same direction, they attract rather than repel each other.

  • Where, μo = permeability of free space.
  • μo = 4π x 10^-7 Tm/A
  • B = magnetic field strength produced at a distance
  • d = distance from the wire
  • I = current

Magnetic Force on a Current Carrying Wire Examples

Question 1: If the first wire has 17 A of current flowing through it, the second wire has 20 A of current flowing through it. Find the magnetic force between two wires if the distance between them is 15 m.

Solution:

Given: Current in the first wire Ia = 17 A

Current in the second wire Ib = 20 A

Distance between two wires d = 15 m

F/L = μ0 x Ia x Ib /(2πd)

= 4π x 10^-7 x 17 x 20/(2π x 15)

= 4.53x 10^-6 N

Hence, the magnetic force between two wires is 4.53x 10^-6 N

FAQs on Force on Current Carrying Wires in Magnetic Field

1. What is the formula for the magnetic force between wires?

F/L = μ0 x Ia x Ib / (2πd) is the magnetic force between two parallel, long, and straight current-carrying wires. F/L stands for force per unit length, d for the distance between wires, and Ia and Ib for current flowing in the first and second wires, respectively.

In the calculator's input boxes, enter the current flow in the first and second wires, as well as the distance between the wires. To quickly compute the magnetic force value, simply press the calculate button.


3. The magnetic force is calculated using which equation?

To calculate the force on a current-carrying wire, Sal uses the formula F=ILB.


4. What is the formula for calculating magnetic fields?

In a magnetic field, the amount of the force on a wire carrying current I with length L is determined by the equation F=ILBsinθ. The force is parallel to the current and the field.


5. What is the relationship between the force on the wire and the magnetic field?

The magnetic force acting on a current-carrying wire is perpendicular to both the wire and the magnetic field, with the right-hand rule directing the direction.
