Magnetism
If two magnets are moving toward each other, you can infer this about the poles.
What is they are opposite?
In order for a copper wire to create a magnetic field this must flow through the wire.
What is electricity?
The electric force between two charged particles is 10N. What is the new force if the charge of one particle is tripled.
What is 30N?
This type of force is only attractive.
What is Gravity?
A type of electromagnet that transfers the electrical energy in the form of AC to DC and change the amount of voltage in a circuit.
What is Transformer?
Moving magnets closer together.
What would increase the magnetic force between magnets?
These two things can be attractive and repulsive.
What are electric and magnetic forces?
Two charged objects have a repulsive force of 10N. If the distance separating the objects is halved, then the new force will be.
What is 40 N?
The Proportionality relationship between force and charge?
What is Directly proportional?
A type of electromagnet that transforms mechanical energy into electrical energy. A magnet is placed in the center of a loop of wire and can rotate freely which causes electricity to flow through the wire.
What is a generator?
The invisible space around a magnet.
What is a magnetic field?
This law can be used to calculate the electric force between 2 charged particles.
What is Coulombs law?
Two balloons are charged with an identical quantity and type of charge: -5.0 C. They are held apart at a separation distance of 12 m. Determine the magnitude of the electrical force of repulsion between them.
What is 1.6*10^9 N
Doubling the charge and halving the distance between two electrically opposite charges.
What will increase the force of attraction?
A type of electromagnet that converts electrical energy into mechanical energy. Electricity flows through a wire that is surrounded by a magnet which causes the wire to spin.
What is a motor?
In order for a magnet to induce an electrical force, it must be doing this.
What is moving?
The space around charged particles?
What is an electric field?
Two balloons with charges of +4.0 C and -9.0 C attract each other with a force of 0.10 Newtons. Determine the separation distance between the two balloons.
What is 1.8*10^6 m
Water behind a dam and energy in a battery.
What are examples of potential energy?
increasing the number of loops in a coil and source of electrical energy will...
What is increase the strength of an electromagnet.
An electrical current induces a magnetic force and this can induce an electrical current.
What is a moving magnetic force?
The motion in a magnetic field causes these to move in an electric wire.
The force between two identical charges separated by 50 m is equal to 100 N. What is the magnitude of the two charges?
What is 0.005 C?
The Proportionality relationship between force and distance.
What is inversely Proportional?
Gravitational, electric and magnetic all use force fields and act at a _______.
What is distance?
