|---|---|---|---|---|---|
| An electrical current that periodically changes direction at a specific frequency. | show 🗑
|
||||
| The temperature at which a permanent magnet loses its magnetic field. | show 🗑
|
||||
| The natural tendency of all matter to weaken a magnetic field, especially in the absence of other kinds of magnetism. These materials generate a magnetic field that opposes the external magnetic field. | show 🗑
|
||||
| Microscopic regions of materials that may be lined up in a single direction to produce a magnetic field of force. | show 🗑
|
||||
| show | electromagnetic induction
🗑
|
||||
| show | ferrimagnetism
🗑
|
||||
| show | geographic north pole
🗑
|
||||
| show | hertz
🗑
|
||||
| A law that says like magnetic poles attract and opposite magnetic poles repel. | show 🗑
|
||||
| show | paramagnetism
🗑
|
||||
| An electrical device used in AC circuits consisting of two coils of wire wound on a single ferromagnetic core, usually shaped like a hollow square. It can either raise or lower the voltage in an AC circuit. | show 🗑
|
||||
| show | ferromagnetism
🗑
|
||||
| show | geomagnetic field
🗑
|
||||
| An object that possesses or can have a magnetic field. | show 🗑
|
||||
| The region of influence surrounding a magnet, where it exerts a magnetic field which is shown by lines of force. | show 🗑
|
||||
| The slowly drifting point on the earth’s surface in the northern hemisphere where the earth’s magnetic field lines are most concentrated and nearly vertical as they pass into the earth’s interior; the south magnetic pole of the earth’s geomagnetic field. | show 🗑
|
||||
| One of two areas of concentrated magnetic field lines on a magnet’s surface. The field direction for each pole is the opposite of the other. | show 🗑
|
||||
| Rule that the direction of the magnetic field surrounding a current-carrying conductor is indicated by the direction the right hand fingers wrap around the conductor, the thumb pointing in the direction of the conventional current flow. | show 🗑
