Magnetic Force
What is a magnetic force?
A magnetic force is the attraction or repulsion that acts at a distance between magnets or magnetic materials.
What are the two types of magnetic poles?
The two types of magnetic poles are north pole and south pole.
What are magnetic field lines?
Magnetic field lines are visual representations of the magnetic field around a magnet, showing the direction and strength of the magnetic force.
What is potential energy in a magnetic field?
Potential energy in a magnetic field is the energy stored due to the position of a magnetic object in the field.
Solve the equation: 12x + 5 = 5x + 6
x = 1/7
How can a magnetic force act at a distance?
A magnetic force can act at a distance through a magnetic field, which extends around the magnet.
How do opposite poles interact?
Opposite poles (north-south) attract each other, while like poles (north-north or south-south) repel each other.
How do magnetic field lines behave around attracting magnets?
Magnetic field lines around attracting magnets point towards each other, indicating attraction.
How does potential energy convert to kinetic energy in magnets?
Potential energy converts to kinetic energy in magnets when a magnet moves closer to another magnet or is released from a position where it was held (exerts a force)
What is the most used makeup product?
Mascara
What happens when like poles of magnets are brought together?
When like poles (north-north or south-south) of magnets are brought together, they repel each other.
What happens when you place two north poles together?
When two north poles are placed together, they repel each other.
Describe the difference in field line patterns for attracting vs. repelling magnets.
Attracting magnets have field lines that connect, while repelling magnets have field lines that separate.
What happens to energy when moving a magnet against a magnetic force?
The energy used to move a magnet against a magnetic force is converted to potential energy stored in the magnetic field.
What are the most popular Mario Kart characters?
Mario & Peach
Describe how a magnetic force can affect energy.
A magnetic force can cause energy changes by converting potential energy stored in a magnetic field into kinetic energy as the magnet moves.
How can you tell if a magnet is a north or south pole?
You can determine if a magnet is a north or south pole by using another magnet; the pole that attracts is the opposite pole.

Describe the energy transfer when attracting magnets are moved closer to each other
If the magnets are free to move, they accelerate toward each other as their magnetic potential energy is converted into kinetic energy due to the attractive force.
What is the most streamed song on Spotify?
"Blinding Lights"
What is the strongest factor affecting magnetic force?
The strength of the magnetic force is affected by the distance between magnets; it is stronger when magnets are closer together.
What is the relationship between pole orientation and magnetic force?
The orientation of the poles determines whether the magnets attract or repel each other.
What does the density of magnetic field lines indicate?
The density of magnetic field lines indicates the strength of the magnetic field; closer lines mean a stronger field.
Describe the energy transfer when repelling magnets are moved closer to each other
The energy remains stored in the system as long as the magnets are held in place. The closer they are, the more magnetic potential energy is stored.
What is the most common gas in the Earth's atmosphere?
Nitrogen
