Calculation path

Calculate magnetic force magnitude on a straight current-carrying wire. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

F=BIL sin(theta)

What you provide

Magnetic field expressed in T, using the same scenario as the other inputs
Wire current expressed in A, using the same scenario as the other inputs
Wire length in field expressed in m, using the same scenario as the other inputs
Field-current angle expressed in deg, using the same scenario as the other inputs

What you receive

Magnetic force in N from the stated equation
A symbolic formula plus substituted working with your values
Visible assumptions, field guidance, and an authoritative learning reference
