Common questions
What is the Magnetic Force on Wire formula?
Magnetic Force on Wire is written F = BILsinθ. Magnetic force on current-carrying wire. It belongs to Electricity & Magnetism, under Magnetism.
What are the units in F = BILsinθ?
In SI units, F is magnetic force, measured in kg·m/s²; B is magnetic field, measured in kg/(A·s²); I is current, measured in A; L is length, measured in m; θ is angle, measured in rad.
How is the Magnetic Force on Wire formula derived?
F = IL × B, magnitude |F| = BIL sin θ. The result is F = BILsinθ.
