Electromagnetism Noun

---

[uh-lek-troh-mag-ni-tiz-uhm]

Back

Electromagnetism

---

A branch of physics involving the study of the combined effects and fundamental interaction between electricity and magnetism.

---

Example: A coil with current creates a magnetic field, showing electromagnetism.

Electric Current Noun

---

[uh-lek-trik kur-uhnt]

Back

Electric Current

---

The rate of flow of electric charge, typically carried by moving electrons through a conductor such as a wire.

---

Example: The image shows electric current as charged particles flowing from a battery through a wire to light a bulb.

Front

Magnetic Field Noun

---

[mag-net-ik feeld]

Back

Magnetic Field

---

The region around a magnet or a current-carrying wire where a magnetic force can be detected by other magnets.

---

Example: The image shows magnetic field lines around a magnet, indicating where magnetic forces can be detected.

Front

Right-Hand Rule Noun

---

[rite-hand rool]

Back

Right-Hand Rule

---

A mnemonic principle used in physics to determine the direction of a magnetic field produced by an electric current.

---

Example: The image shows how to use the right-hand rule to find the direction of a magnetic field around a current.

Front

Solenoid Noun

---

[soh-luh-noid]

Back

Solenoid

---

A coil of wire with an electric current flowing through it, which acts as a magnet when energized.

---

Example: A solenoid is shown with a coil of wire and magnetic field lines, demonstrating how it acts as a magnet when current flows through it.

Front

Tesla Noun

---

[tes-luh]

Back

Tesla

---

The standard international (SI) unit of measurement for the strength or density of a magnetic field.

---

Example: The image shows magnetic field lines around a bar magnet, illustrating field strength measured in teslas.

Front

Ferromagnetic Material Noun

---

[fer-oh-mag-net-ik muh-teer-ee-uhl]

Back

Ferromagnetic Material

---

A substance, such as iron, nickel, or cobalt, that has strong magnetic properties and can be easily magnetized.

---

Example: A bar magnet shows how ferromagnetic materials like iron can be magnetized with north and south poles.

Front

Electromagnet Noun

---

[uh-lek-troh-mag-nit]

Back

Electromagnet

---

A type of magnet created by passing an electric current through a wire coil, often wrapped around a ferromagnetic core.

---

Example: An electromagnet is shown with a coil wrapped around a core, illustrating how electric current creates a magnetic field.

Front

Magnetic Compass Noun

---

[mag-net-ik kum-puhs]

Back

Magnetic Compass

---

An instrument with a magnetized pointer that aligns with Earth's magnetic field to show the direction of magnetic north.

---

Example: A magnetic compass uses a magnetized needle to align with Earth's magnetic field, showing north.

Front

Maglev Noun

---

[mag-lev]

Back

Maglev

---

A transportation system, like a train, that uses powerful magnetic forces for levitation and propulsion without touching a track.

---

Example: The image shows a maglev train levitated by magnetic forces, illustrating how it floats above the track without touching it.
