Electromagnetic Force - Definition
When an electric current flows through a wire and a magnetic field surrounds it, the moving electrons feel the force. The other name for this force is the electromagnetic force.
Electromagnetic Force on Current-Carrying Wire Equation
Following is the formula for calculating the strength of the magnetic force operating on a straight current-carrying wire.
F = I x B x L x sin(α)
I = F/(B x L x sin(α))
B = F/(I x L x sin(α))
- F = magnetic force of the wire
- I = current flowing through the wire
- L = length of the wire
- B = strength of the magnetic field
- α = angle formed by the current direction and the magnetic field direction.
How to Calculate Magnetic Force on a Straight Wire?
The steps for obtaining electromagnetic force on a straight current-carrying wire are as follows. To check the result in a short period, follow these simple procedures.
- Step 1: Examine the amount of current flowing through the wire, the magnetic field's strength, the wire length, and the angle between the current and the magnetic field.
- Step 2: Multiply the current, magnetic field, and wire length.
- Step 3: Calculate the angle value's sine function.
- Step 4: To check the magnetic force, multiply the product by the result.

Example on Electromagnetic Force on Current-Carrying Wire
Question 1: A magnetic field exerts a force of 8.0 x 10^-3 N in the positive y-direction on a wire of length 1.5 m carrying an electric current of 0.7 A is perpendicular to the magnetic field and in the negative direction. Calculate the magnitude.
Length of the wire L = 1.5 m
Current I = 0.7 A
Magnetic force F = 8.0 x 10^-3 N
Angle α = 90°
B = F/(L x I x sin(α))
B = (8.0 x 10-3)/(1.5 x 0.7 x sin(90°))
= 7.61 x 10^-3
Therefore, the strength of the magnetic is 7.61 x 10^-3 T.

FAQs on Electromagnetic Force on Current-Carrying Wire
1. On a current-carrying wire, what is the magnetic force?
F = IL x B is the magnetic force on a current-carrying wire in a magnetic field. When a current flows through a magnetic field, the magnetic field acts on the wire in a direction that is perpendicular to both the current and the magnetic field.
2. Is a magnet affected by a current-carrying wire?
A permanent magnet can be acted upon by a current-carrying wire or coil. If the magnetic field strength and/or current increase, the force increases.
3. What happens if you put a current-carrying wire next to another current-carrying wire?
When a current-carrying conductor is put in a magnetic field, it is subjected to a mechanical force that can cause the conductor to move.
4. What forms around the wire when current travels through it?
When an electric current passes through a wire, it heats (current heating effect) and creates a magnetic field around it ( magnetic effect of current).
5. Is it possible for a current-carrying wire to be neutral?
The rate of flow of charges, or electrons, is known as current. As a result, a current-carrying wire is electrically neutral.
