Across
- 8. a piece of iron (or an ore, alloy, or other material) that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.
- 9. a cylindrical coil of wire acting as a magnet when carrying electric current.
- 10. a force that acts between moving surfaces.
- 12. a vector field that describes interaction between moving electric charges (that is, electric currents), and magnetic materials.
- 17. In electricity generation, a generator is a device that converts motive power into electric power for use in an external circuit.
- 18. Electromagnetism is the physical interaction among electric charges, magnetic moments, and the electromagnetic field.
- 19. the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
- 21. an influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration.
- 23. a region in which each point is affected by a force.
- 25. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
- 26. the vector sum of all the forces that act upon an object.
- 29. to pull an object slowly or heavily
Down
- 1. substances with properties somewhere between them.
- 2. A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
- 3. a force that keeps an object at rest.
- 4. the production of an electromotive force across an electrical conductor in a changing magnetic field.
- 5. force of attraction or repulsion between substances made of certain materials
- 6. each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.
- 7. the energy of either an object in motion or the energy that is stored in objects by their position.
- 11. An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
- 13. a natural phenomenon by which all things with mass or energy, including planets, stars, galaxies and even light, are attracted to (or gravitate toward) one another.
- 14. free fall is any motion of a body where gravity is the only force acting upon it.
- 15. a form of energy that an object or a particle has by reason of its motion.
- 16. an imbalance of electric charges within or on the surface of a material or between materials
- 20. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
- 22. an orbit is the curved trajectory of an object
- 24. a substance in which electrical charge carriers, usually electrons, move easily from atom to atom with the application of voltage.
- 27. a material in which electric current does not flow freely.
- 28. An electric motor is an electrical machine that converts electrical energy into mechanical energy.
