Exploring the Strength of Magnetic Force

Front

Attract Verb

---

[uh-trakt]

Back

Attract

---

To exert a force that pulls an object closer, such as the one occurring between opposite magnetic poles.

---

Example: This diagram shows two bar magnets where the opposite poles (North and South) are facing each other, causing them to pull together or attract.

Front

Convert Verb

---

[kun-vurt]

Back

Convert

---

To change something from one form to another, such as transforming potential energy into kinetic energy.

---

Example: This diagram shows a generator converting mechanical energy (the spinning coil) into electrical energy, which lights up the bulb.

Front

Electromagnet Noun

---

[uh-lek-troh-mag-nit]

Back

Electromagnet

---

A magnet created by an electric current flowing through a wire, which can be activated or deactivated.

---

Example: This image shows how an electromagnet is made by wrapping an insulated wire around an iron core (a nail) and connecting it to a battery.

Front

Energy Noun

---

[en-er-jee]

Back

Energy

---

The capacity to cause change or do work, which can be stored or associated with an object's motion.

---

Example: A ball at the top of a ramp has stored potential energy, which changes to kinetic energy (energy of motion) as it rolls down.

Front

Force Noun

---

[fors]

Back

Force

---

A push or a pull exerted on an object that can cause a change in its motion or state.

---

Example: A person applies a force (a push) to move an object, with the arrow showing the direction of the force.

Front

Kinetic Energy Noun

---

[ki-net-ik en-er-jee]

Back

Kinetic Energy

---

The form of energy that an object possesses as a result of its motion.

---

Example: As the ball is released and falls, its stored potential energy is converted into kinetic energy, which is the energy of an object in motion.

Front

Magnetic Field Noun

---

[mag-net-ik feeld]

Back

Magnetic Field

---

The region surrounding a magnet where its magnetic force can be detected and can influence other objects.

---

Example: This image shows the invisible magnetic field around a bar magnet, with arrows pointing from the North pole to the South pole.

Front

Magnetic Field Lines Noun

---

[mag-net-ik feeld lainz]

Back

Magnetic Field Lines

---

Imaginary lines that map the direction and strength of the magnetic field surrounding a magnet.

---

Example: This diagram shows a bar magnet with North (N) and South (S) poles. The arrows on the lines show the magnetic field flowing from North to South.

Front

Magnetic Pole Noun

---

[mag-net-ik pohl]

Back

Magnetic Pole

---

One of two points, designated North or South, on a magnet where its magnetic force is most concentrated.

---

Example: This diagram shows a bar magnet with its North (N) and South (S) poles, and the magnetic field lines that flow from North to South.

Front

Model Noun

---

[mod-l]

Back

Model

---

A representation of an object, system, or event used to explain and understand complex scientific phenomena.

---

Example: This diagram is a scientific model that simplifies the Moon's orbit, showing how Earth's gravity pulls on the Moon, keeping it in a path.
