Students attached both ends of a long wire to the poles of a battery and wrapped the wire around a nail. In this arrangement, the nail is able to pick up five paper clips.
The students wrap more wire around the iron and wanted to determine if the strength of the magnetic force has increased. Which of the following observations would indicate that wrapping more wire has increased the strength of the electromagnet?
More wire was needed to wrap around the spoon.
The nail now picks up seven paper clips.
Eventually, the battery runs out of energy.
The ends of the wire must touch the battery's poles.
What is the benefit of having a Electromagnet
The power source is larger
You can turn it on and off
It uses conductive wire
I don’t know
What happens when an electric current flows through a wire?
The wire begins to spin.
Nothing happens.
A field of gravity is created around the wire.
A magnetic field is created around the wire.
As the strength of a magnetic field increases, the ability to attract metal objects ____________.
increases

When does an object have no kinetic energy?
When it's at rest.
When it's moving very slowly.
When the only force that's acting on it is gravity.
When it has no electrical charge.
Why do objects at high elevations have more potential energy than objects at low elevations?
Because the thinner air at higher elevations means objects have a greater potential to move very fast
Because objects at high elevations are closer to the sun, which is the source of all energy on earth
Because objects at high elevations tend to move slower than objects at low elevations
Because gravity gives objects at high elevations the potential to fall much further
How could you increase the gravitational potential energy of an object without changing its mass?
Make the object larger
Lower the object towards the ground
Raise the object farther off the ground
Allow the object to roll on the ground

up on the roof
down in the basement
in the middle
outside
Which object will have the largest value for its potential energy?
