Space and Magnetism Flashcards
The area around the magnet electric current or moving charged particle where there is a magnetic force
Magnetic field
Magnetic field lines are drawn acting towards this pole of a permanent magnet
South
A U-shaped permanent magnet with a magnetic pole at each end
Horseshoe
The left-hand rule used to determine the relative orientation of the force the current in the conductor and the magnetic field causing the motor effect is named after this scientist
Fleming
This word describes the shape of the magnetic field around a current carrying wire
Circular
This acts on a conductor in the direction represented by the thumb when using Fleming’s left-hand rule
Force
This word describes a material that can be attracted by a magnet. Examples are iron, steel, nickel and cobalt.
Magnetic
A force that causes two unlike magnetic poles to move toward each other
Attraction
A material only becomes this type of magnet when it is placed in a magnetic field
Induced
A magnetic metal that can be used as the core of an electromagnet
Iron
The direction in which this flows through a conductor is represented using the middle finger in Fleming’s left hand rule
Current
Magnetic field lines are drawn acting away form this pole of a permanent magnet
North
This word describes a magnet that produces its own magnetic field
Permanent
The rule showing the direction of the magnetic field around a current-carrying wire when the fingers are curled into the palm and outstretched thumb is aligned with the direction of the current
Right hand grip
A device containing a small bar magnet that points in the direction of the Earth’s magnetic field
Compass
