Explanation:
The Biot-Savart Law can be used to determine the magnetic field strength from a current segment. For the simple case of an infinite straight current-carrying wire it is reduced to the form B=μ0I2πr B = μ 0 I 2 π r . ... A current-carrying wire feels a force in the presence of an external magnetic field.
