Which claim does Jordan's evidence support?

A magnetic force is stronger closer to a magnet.

Electromagnets do not have magnetic fields.

Magnetic fields are stronger further away from the magnet.

What's one thing Jordan could do to make the sensor unlock the door?

Move his badge closer to the sensor.

Place his badge in his jacket pocket

Walk as far from the sensor as possible

The school decides to try to increase the strength of the electromagnet so the badge sensor will work better. Choose all the ways to increase the strength of an electromagnet.

Increase the number of wire wraps.

Increase the voltage of the electromagnet

Move the electromagnet closer to where the students walk

Use less coils on the electromagnet

What happens if you reverse the battery connections on an electromagnet?

The electromagnet’s magnetic field reverses, causing a magnet that was attracted to now be repelled.

Nothing changes; the electromagnet works the same way regardless of battery direction.

The electromagnet gets stronger because reversing the battery increases the energy transferred

The electromagnet stops working because energy is no longer transferred.

How do magnetic field lines indicate the strength of a magnetic field?

The closer the field lines are to each other, the stronger the magnetic field.

The farther apart the field lines are, the stronger the magnetic field.

The length of the field lines determines the strength of the magnetic field.

The color of the field lines changes based on field strength.

Jamal is building an electromagnet for a science fair project to lift small metal objects. At first, it works, but it’s not strong enough to pick up heavier nails. Jordan wants to adjust the battery to make the electromagnet stronger. Which of the following changes would most likely help? Select all that apply.

Add a second battery to increase power.

Use a battery with a higher voltage.

Nothing about the battery can be changed to make the electromagnet stronger.

Maya shuffles her feet on a carpet and then reaches toward a small piece of tissue on a table. When her hand is far away, nothing happens, but as she moves her hand closer, the tissue suddenly lifts off the table and sticks to her fingers. Which statement best explains why the tissue does not move when Maya’s hand is farther away?

The electric field from Maya’s hand is weaker when it is farther away from the tissue.

The tissue is not affected by static electricity.

Maya’s hand and the tissue have the same type of charge, so they repel each other.

Static electricity only works with metal objects.

When a bar magnet causes an electromagnet to move , what type of energy conversion takes place?

Potential energy is converted into kinetic energy.

Kinetic energy is converted into electrical energy.

Kinetic energy is converted into potential energy.

Electrical energy is converted directly into kinetic energy, skipping potential energy.

Students observe that the magnetic field lines at the electromagnet’s north pole and the bar magnet’s south pole change very little when the magnets move closer or farther apart. Which statement best explains this observation?

Some areas of a magnetic field stay strong, especially where the poles interact.

Magnetic force does not depend on distance.

The electromagnet’s field is unaffected by the bar magnet.

Magnetic fields only exist when magnets touch.

What factor affects the potential energy between an electromagnet and a bar magnet?

The distance between the magnets

The strength of the magnets but not their distance.

The type of metal used in the magnets but not their position.

The potential energy remains constant regardless of how close or far apart the magnets are.

In this image, matching north poles from two magnets are introduced. What do you predict will be the outcome?

There will be no interaction. The poles of magnets do not have an effect on one another.

There will be a field of repulsion, and they will move away from each other

There will be a field of attraction, and they will move towards each other

Samantha wants to make her electromagnet stronger. First, she uses 20 coils and a battery. Then, she tries again with more coils and a stronger battery. The magnet picks up more paperclips, but she isn’t sure why.
What was her mistake?

She changed two variables at once, so she doesn’t know which one made it stronger.

She didn’t test it enough times.

She should have used fewer coils.

Paperclips aren’t a good way to measure strength.
