Oersted’s experiment Oersted, a Danish physicist, accidentally discovered the occurrence of a magnetic field around a current-carrying wire. Oersted said that he was surprised to see the compass’s magnetic needle placed next to the wire rotate while experiment to show … more
Assuming that the current flowing in the wire is in the X-direction, the magnetic field is in the Y direction. Then, what direction is the electromagnetic force? ‘Homopolar motor’ refers to a motor operated by using only one polarity of … more
Direction of the Lorentz force Conductors in which current flows in a magnetic field are forced to move. The direction of this force is perpendicular to the current and the magnetic field, respectively. More precisely, we can find out below. … more
