A magnet is an object that attracts certain materials, usually objects that are made of:
plastic
glass
iron or steel
rubber
A magnet has two ends called:
We call the end of the magnet a north pole if it points to the earth's ___________ pole
South magnetic
North magnetic
center
A force that exists between two magnetic poles is called a ___________ force.
We call the space all around a magnet where the magetic force can act a ____________ .
electric field
gravitational field
magetic field
field of dreams
The Earth's iron core acts like a giant bar magnet. The poles of this bar magnet are located near the Earth's North geographic pole and the South geographich pole. When you hold a bar magnet, you notice that the bar magnet's North pole is pointng towards the Earth's North pole. Since you know that the poles of magnets are attracted to the oppposite pole of another magnet, which pole of the Earth's gigantic bar magnet is actually located at what we call the 'North pole'?
The Earth bar magnet's North pole
The Earth bar magent's South pole
You have two magnets. One magnet's poles are labeled North and South. The other magnet is not labled. You bring the second magnet close to the first magnet's North pole. The two magnets are drawn together until they actually touch. Which pole of the second magnet is touching the North pole of the first magnet?
South pole
North pole
The pull of a magnet is strongest at the magnet's _____________ .
Field lines around a magnet show the lines of __________ .
A compass needle points along an imaginary magneitc field force line connecting the Erath's North and South magnetic poles.
True
False
Magnet fields have different shapes. Which type of magnet has a magentic field that is about the same shape as the Earth's magnetic field?
U shaped magnet
Circular magnet
Bar magnet
The picture below shows the magnetc field lines between the two closest poles of two bar magnets. The pole of the bar magnet on the left is the North pole. The pole of the bar magnet on the right must be the ___________ .
North pole
South poile
The picture below shows the magnetc field lines between the two closest poles of two bar magnets. The pole of the bar magnet on the left is the North pole. The pole of the bar magnet on the right must be the ___________ .
