Two aluminum balls are 5 cm apart. One is negatively charged, and the other is positively charged. A small magnet is placed between the two balls but is not touching either of them. The aluminum balls remain stationary. Which statement describes the electric and magnetic fields?
There is a magnetic field due to the magnet and no electric field.
There is a magnetic field between the two balls and no electric field.
There is an electric field between the two balls and no magnetic field.
There is an electric field between the two balls and a magnetic field due to the magnet.
A positively charged pith ball is hanging from a string. A negatively charged rod is then held a short distance away. How will the pith ball be affected?
It will not be affected because only the rod has an electrical field.
The fields on the pith ball and the rod will interact, causing an attractive force.
The fields on the pith ball and the rod will interact, causing a repulsive force.
It will not be affected because the pith ball and the rod are not touching.
Which of these best describes a magnetic field?
a measure of the length of a magnet
the force that pushes two magnets away from each other
an invisible area that surrounds the north pole of a magnet
an area around a magnet in which magnetic forces can be measured
Stephan claims that Earth has both a gravitational field and a magnetic field. Which statement best supports his claim?
Any object will fall to the ground.
A bar magnet will fall to the ground.
Any object will fall to the ground, and a compass can be used for navigation.
A compass points in the direction of both the magnetic and gravitational fields.
A student is brushing her hair. As the hairbrush is brought near her head, the hair seems to reach toward the hairbrush. Which of the following is the best explanation?
Two electric fields are interacting.
Two magnetic fields are interacting.
Two gravitational fields are interacting.
Two electromagnetic fields are interacting
A student is conducting a scientific investigation using iron filings to show the magnetic field of magnets. She examines the magnet surrounded by filings.
Will the iron filings attract or repel?
What shape of magnetic field lines does a bar magnet display?
What is the furthest distance the filings will land?
