Electric Field
A field in which a magnetic force exists.
Magnetic Field
Points to the northern position on the earth's surface that the earth's axis of rotation passes through.
Geographic north
Is a magnetic field 2-dimensional or 3-dimensional?
3 dimensional
What is significant about Palm Sunday?
Palm Sunday marks Jesus Christ’s triumphant entry into Jerusalem.
Representation of an electric force, showing the direction the force would have on a positive charge.
A type of material that is strongly attracted by magnets.
Ferromagnetic
The northern magnetic pole of the earth's magnetic field.
magnetic north
An electron is a charge that moves about the
nucleus
What holiday is being celebrated when Jesus makes his return to Jerusalem?
Passover
The two ends of a magnet, where most of the magnetic force is centered.
Magnetic Poles
A type of material is somewhat attracted by magnets.
Paramagnetic
Loops of wire that are coiled together, and produce a magnetic field when current is passed through it.
Solenoid
The flow of anything in a given direction
current
What is significant about Maundy Thursday?
The Lord’s Supper was instituted on this day.
Tiny regions of magnetic force in ferromagnetic materials.
Domains
Natural materials that produce a magnetic field.
Ferrimagnetic
A device that uses a solenoid to operate a switch than can open or close another circuit.
Relay
When charged particles flow through the conductor, we call it what
Current electricity
According to Scripture, who arrived first on Easter Sunday at Jesus’ grave?
Mary Magdalene
The temperature at which a ferromagnetic material becomes paramagnetic, or loses its magnetic field
Curie temperature
An electric current that periodically reverses the direction that it flows.
Alternating current
A constant electric current that always flows in one direction.
Direct current
Explain why an AC motor would need a split ring
In a DC motor, the purpose of the split ring is to alternate the current, which reverses the magnetic field in the armature and keeps the motor spinning. An AC current is already alternating, so AC motors don't need a split ring.
When did Jesus tell his disciples that he would be betrayed?
After two days
