|---|---|---|---|---|---|
| magnet | material that attracts iron
🗑
|
||||
| magnetic pole | one of two points such as the ends of a magnet that have opposite magnetic properties
🗑
|
||||
| magnetic force | the force of attraction or repulsion created by moving or spinning electric charges
🗑
|
||||
| atoms | a very small building blocks of matter
🗑
|
||||
| domains | small sections of atoms that are lined up to make a magnetic field
🗑
|
||||
| ferromagnets | magnets made or iron, cobalt, and nickel
🗑
|
||||
| temporary magnets | easy to magnetize, but doesn't stay magnetized for long
🗑
|
||||
| permanent magnets | difficult to magnetize, but remain magnetized for longer amounts of time
🗑
|
||||
| Earth's core | the area of the earth with moving iron that creates our magnetic field...not every planet has this
🗑
|
||||
| aurora | a curtain of lights which result from solar wind burning up in the atmosphere at the poles
🗑
|
||||
| electromagnetism | interaction of electricity and magnetism
🗑
|
||||
| solenoid | a coil of wire with an electric current running through it...creates a magnetic field
🗑
|
||||
| electromagnet | a solenoid with a iron core...strong magnetic field
🗑
|
||||
| electric motor | changes electrical energy to mechanical energy (it can do work)
🗑
|
||||
| electric generator | changes mechanical energy (work of machines) to electrical energy
🗑
|
||||
| electromagnetic induction | creating electrical current by moving a magnetic field past a coil of wires
🗑
|
||||
| Hans Christian Oersted | (1820) discovered that moving charges (electricity) can create magnetic fields
🗑
|
||||
| how to strengthen electromagnets | More loops of wire - More electricity - More metal in the core of the solonoid
🗑
|
||||
| types of turbines | wind - water - geothermal - nuclear ----- all of them turn to generate electricity by passing magnets by wires to move electrons
🗑
|
||||
| north geographic pole ("top" of the Earth) | south magnetic pole
🗑
|
||||
| Michael Faraday | (1831) discovered that changing magnetic fields (moving magnets) make electrons flow in wires (electricity)
🗑
|
||||
| types of magnets | ferromagnets, electromagnets, permanent, temporary
🗑
|
||||
| how to "mess up" a magnet | store it with other magnets in a disorderly way - extreme heat - dropping it - hitting it
🗑
|
||||
| how to create a magnet | rub a magnet against the iron, nickel, or cobalt to line up the atoms into organized domains....get the atoms to line up
🗑
|
||||
| electrons | particles in the outside area of the atom.....when they move and go from atom to atom we call it "electricity"
🗑
