What is magnetic force? One of two points, such as the ends of a magnet, that have opposing magnetic qualities What is magnetic pole? A device that converts mechanical energy into electrical energy. What is an electric generator? A device that converts electrical energy into mechanical energy. What is an electric motor? The interaction between electricity and magnetism. What is electromagnetism? The process of creating a current in a circuit by changing a magnetic field. What is electromagnetic induction? Any material that attracts iron or materials containing iron. What is a magnet? A device that increases or decreases the voltage of alternating current. What is a transformer? Whether a material is magnetic or not depends on this. What is the material’s atoms? As electrons move they make this. What are magnetic fields? By increasing the electric current in the wire you are also doing this to the solenoid. What is increasing the magnetic field? A galvanometer uses this to make the relationship between electric current and magnetic fields. What are magnets? What can you make visible by sprinkling iron filings around a magnet. What are magnetic field lines? Faraday’s experiments showed that magnetic fields are made when the electric field does this. What is changes. A compass needle responds to a magnetic field, because the compass needle is this. What is a magnet? This is created when a magnet moves through a coil of wire. What is an electric current? This is created when a wire moves between the poles of a magnet. What is an electric current? This will demagnetize a magnet. What is heat or drop? A coil of wire with an electric current is called this. What is a solenoid? A coil of wire that has a soft iron core that acts as a magnet when an electric current is in the coil is this. What is an electromagnet? Increasing the number of loops per meter in the solenoid does this to it. What is strengthen the solenoid’s magnetic field? A step-up transformer has more coils in this. What is the secondary coil? Compasses work because the earth acts like this. What is a magnet? A step-down transformer has more coils in this. What is the primary coil?
