3. magnetic field produced by the induced current is in the direction that is opposite the original field
6. an instrument that measures the charge-to-mass ratio of positive ions within a material
9. A discontinuous circuit through which no current can flow is called
12. wire connected to a circuit and coiled into many spiral loops
14. A device used to transfer electrical energy from one circuit to another
15. when there is an unbroken path on which electrons flow it is called a
16. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons

1. Law states a relationship between voltage ,current, and resistance
2. an electric current flowing in one direction only
4. generated in any piece of metal moving through a magnetic field; the magnetic they produce opposes the motion that caused the currents
5. SI unit: A
