The electric motor - An electric motor is a device where you input current to a loop (or stack of loops) and get out rotational motion. Attatched picture depicts the behavior of a current loop in a magnetic field: assume the magnetic field at the location of the loop is upwards, as shown below. Each of the picture shows the loop at different orientations, with currents indicated by x&o.   a. If the battery (battery pack) is connected to the two terminals of the working DC motor, what would happen? Also what would happen if the direction of current through the motor is switched? b. At the components in the "taken apart" DC motor, what is creating magnetic field? Where is the current loop? Can you please sketch and label the part

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
