Answer the following statement(s) true (T) or false (F)
1. The principle of electro-magnetism states that when an electrical current flows through an electrical conductor, a magnetic field will be created around that conductor. 2. The strength of the magnetic field created by an electromagnet is determined by the magnetic polarity. 3. The magnetic polarity of an electromagnetic field is determined by the direction of current flow through the coil. 4. The greater the magnetic flux density, the lower the induced voltage will be. 5. Lenz’s Law states that an induced voltage will be the opposite polarity as the electrical source voltage that created it.
