If a wire is moved near a magnet
WebThe magnetic force on a current-carrying wire in a magnetic field is given by F → = I l → × B →. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sin θ = 1. WebTools. A simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created. [1] The strength of magnetic field generated is proportional to the amount of current through the winding. [1] Magnetic field produced by a solenoid (coil of wire).
