Magnetic Fields
This magnetic field between two magnets flows in one direction.
What is an attractive magnetic field?
This current travels through a coil when connected to a powersource.
What is an electric current?
A pushing force between magnets.
What is a repulsion?
What is a magnet?
Variable that does not change, typically is used as a baseline
What is a control?
This magnetic field between two magnets flows from two, opposite directions, causing an invisible barrier in between
What is a repulsive magnetic field?
A magnet has an attractive force with the electromagnet. A flip of the electric current causes this.
What is a repulsion?
A pulling force between magnets or between a magnet and some types of metals.
What is an attraction?
This is a type of magnet that always has a magnetic field.
What is a permanent magnet?
The variable that changes depending on the independent variable
What is the dependent variable?
This is always present around a permanent magnet.

Forces are affected by this variable between the magnets.
What is the distance?
The variable in an experiment that you change when testing
What is the independent variable?
The shape of a magnetic field around a magnet.
What is an oval?
Flipping the current's direction in the coil, always causes this to flip.
What is the magnetic force/field?
The brightness of a LED connected to a computer is affected by this.
What is the volume and frequency of the sound?
The two poles that are on a magnet.
What are north pole and south pole?
Find the independent variable: Testing different metals to see what works best as an electromagnet.
What is different types of metals?
A constant flip of magnetic fields causes this in a speaker.
These particles are what flows through a wire to form an electric current.
What are electrons?
The poles on a magnet are attractive when they are this.
What is opposite?
This is how forces act on each other.
What are equal and opposite forces?
Find the dependent variable: Testing different metals to see what works best as an electromagnet.
