Magnets have two ends called poles. Each pole of a magnet applies a force to the poles of other magnets. In this picture, you can see small black pieces of metal. They show the force field of each magnet.The force from the north pole of Magnet 1 pushes the north pole of Magnet 2.What is the direction of this force?away from Magnet 1toward Magnet 1Submit

The force around a magnet can be drawn as a 2D diagram. Determine which two of the following correctly describe the lines that show force around a magnet. The lines can cross overWhere the lines are further apart, the magnetic force is weakerThe lines have arrows to show whether the magnetic force is a push or a pullThe lines have arrows that point away from the north pole, towards the south pole

Select the correct answer from each drop-down menu.Two magnets are placed as shown in the image.The force of between the poles B and C is . And the force of between the poles A and D is .

What are the two centers of magnetic force located near each end of the magnet called?PolesSpectrumsDomainsFields

What will happen when the north pole of one bar magnet is brought close to the north pole of a second bar magnet?There will be an attractive force between the two north polesThe magnets will accelerate towards one anotherThere will be no force between the two north polesThere will be a repulsive force between the two north poles2A student is experimenting with a bar magnet and a plotting compass.  As she moves the plotting compass around the bar magnet, the needle inside the compass rotates.  Which one of the following statements is correct?The needle always points opposite to the direction of the magnetic fieldThe needle always points directly towards the north pole of the bar magnetThe needle always points directly towards the south pole of the bar magnetThe needle always points in the direction of the magnetic field3Which of the following statements is incorrect?The Earth’s magnetic south pole is in the Southern HemisphereThe magnetic field of the Earth is stronger at the poles than it is at the EquatorThe magnetic field of the Earth (and any magnet) is stronger where the field lines are closer togetherAs long as there aren’t any strong magnets nearby, a compass needle will always point in the direction of the Earth’s magnetic field4Which of the following statements about permanent magnets is incorrect?They produce their own magnetic fields and always have a north pole and a south poleThe force between two permanent magnets will increase when they are brought closer to one anotherThey can be attracted to or repelled by other permanent magnetsUnder certain circumstances, they will only be attracted to other permanent magnets5An iron nail is initially unmagnetised.  Which one of the following things will occur when it is brought closer to the north pole of a permanent bar magnet?Nothing will happen since the iron nail is not a permanent magnetThe iron nail will be repelled by the bar magnetThe iron nail will be permanently magnetisedThe end of the nail which is placed closest to the north pole of the bar magnet will become an induced south pole

Which types of magnet have two poles close to each other?
