MS-PS2-5: Magnetic and Electric Fields

Front

Magnetic Force Noun

---

[mag-net-ik fors]

Back

Magnetic Force

---

The force of attraction or repulsion that a magnet exerts on another magnet or on a magnetic material.

---

Example: Arrows show magnetic force lines around a magnet, illustrating attraction and repulsion.

Front

Magnetism Noun

---

[mag-ni-tiz-um]

Back

Magnetism

---

An invisible natural force that causes magnets to attract or repel certain materials, similar to the force of gravity.

---

Example: The image shows how opposite poles of magnets attract each other, illustrating the concept of magnetism.

Front

Magnetic Field Noun

---

[mag-net-ik feeld]

Back

Magnetic Field

---

The invisible area of force that extends from a magnet into the surrounding space, exerting magnetic influence.

---

Example: The image shows magnetic field lines around a bar magnet, illustrating the invisible area of force.

Front

Gravitational Field Noun

---

[grav-i-tey-shun-ul feeld]

Back

Gravitational Field

---

An invisible field of force extending from an object due to its mass, which causes gravitational attraction.

---

Example: Arrows show Earth's gravitational field pulling objects towards it.

Front

Poles Noun

---

[pohls]

Back

Poles

---

The two opposite ends of a magnet, designated as north and south, where the magnetic force is strongest.

---

Example: The image shows Earth's magnetic poles with a bar magnet, highlighting the north and south poles where magnetic force is strongest.

Front

Attract Verb

---

[uh-trakt]

Back

Attract

---

To pull another object closer, which occurs in magnetism when opposite poles are brought near each other.

---

Example: Opposite poles of magnets attract each other, shown by arrows pointing together.

Front

Repel Verb

---

[ri-pel]

Back

Repel

---

To push another object away, which occurs in magnetism when two like poles are brought near each other.

---

Example: Two magnets with like poles facing each other show repulsion.

Front

Permanent Magnet Noun

---

[pur-muh-nent mag-net]

Back

Permanent Magnet

---

A magnet that retains its magnetic properties for a long time due to the stable alignment of its particles.

---

Example: A bar magnet with visible magnetic field lines shows how a permanent magnet retains its magnetic properties.

Front

Induced Magnetism Noun

---

[in-doosd mag-ni-tiz-um]

Back

Induced Magnetism

---

The temporary magnetism created within a magnetic material when it is placed inside an external magnetic field.

---

Example: A coil wrapped around a metal core shows how a magnetic field induces magnetism in the core.

Front

Temporary Magnet Noun

---

[tem-puh-rair-ee mag-net]

Back

Temporary Magnet

---

A material that acts as a magnet only when it is within the magnetic field of another magnet.

---

Example: A magnet attracts paperclips, showing temporary magnetism when in a magnetic field.
