Physics for IGCSE & O level - Magnets And Currents (Section 11 - No. 15)
How can the force on a current-carrying wire in a magnetic field be increased?
Increasing the current
Increasing the strength of the magnetic field
Increasing the length of wire
Reversing the polarity of the magnet
Explanation
The force on the wire can be increased by increasing current, the strength of the magnetic field, or the length of wire.
