Electric Force
The force between charged objects
What is electric force?
The end or ends of a magnetic object, where the magnetic force is strongest.
What is the Magnetic Poles?
The relationship between electricty and magnetism.
What is electromanetism?
A device that uses an electromagnet to detect small amounts of current.
What is a galvanometer?
An increase in the number of magnets within an electric motor will do this to the speed of the motor.
What is increase?
Negatively charge particles in an atom.
What are electrons?
A region around a magnet where the magnetic force is exerted.
What is a Magnetic field?
A coil of wire with electricity running through it is called this
What is a Solenoid?
This transforms mechanical energy into electric current?
What is a generator?
If an neutral atom of a substance has 10 electrons, how many protons does it have?
What is 10?
The electrons are more tightly bound to their atoms in these materials.
What are insulators?
The distance between magnetic field lines indicates this.
What is the strength of the Magnetic field?
Looping a wire with a current running through it will do this.
What is the magnetic field will grow stronger?
This type of current only flows in one direction?
What is direct current?
You would need to do this in order to increase the magnetic strength of a solenoid.
When two like electrical charges push away from one another this decreases
What is potential energy?
Auroras show evidence that this is working to protect us.
What is Earth's Magnetic field?
These 3 elements are ferromagnetic.
What are iron, nickel, and cobalt?
The process of generating an electric current form the motion of a conductor through a magnetic field.
What type of transformer do I need for a 15v phone charger?
This acts like a force that causes current to flow through a circut.
What is voltage?
When a plane takes off, it is affected by this type of potential energy.
What is Gravitational PE?
In your headphones, an electromagnet helps to produce these to carry the sound to your ears.
What are vibrations?
In an electric motor, this is a loop of wire that current flows through.
What is the armature?
A step down transformer has ten loops in the primary coil and six in the secondary. If the incoming voltage is 120 volts, what is the outgoing voltage?
What is 72 volts?
