Introduction to Electromagnetics lab assignment

1. If a metal rod in the solenoid tune were replaced with a cylindrical magnet, as in some power door locks, how could you make the rod move in and then move out, to lock and unlock?

2. Explain how a wire loop, which is known as an armature in an electric motor, is induced to spin by the placement of a permanent magnet beneath it.

3. Explain why coils move in the opposite direction when the permanent magnets are turned over?

(1) These locks are made of electromagnets and an armature shield. An armature is made of many loops mounted on a shaft or axle. The magnet is installed inside a wall above the door and the armature plate on the front of the door. When they are connected to a power source, the magnet and the plate are held together by a very strong magnetic connection that does not allow the door to be opened.

The locks are based on electromagnetism which means that a current is run through a solenoid and a magnetic force is created. For auto door locks, the magnetic force created keeps the door closed tight because of the armature plate and the electromagnet are connected. To make the door closed more tightly, all you have to do is add solenoids.

The more magnetic force, the stronger the lock will be. The magnets are made to be \"fail-safe\", and companies are smart and run the current through the electricity that is connected to the entire building, so if the power were to shut down, the doors would automatically be open so everyone can leave without problem.

(2) The armature\'s role is to carry current crossing the field, thus creating shaft torque in a rotating machine or force in a linear machine

As the magnet spins, the magnetic field around the top and bottom of the coil constantly changes between a north and a south pole. This rotational movement of the magnetic field results in an alternating emf being induced into the coil as defined by Faraday’s law of electromagnetic induction.
