What is the magnetic field?
A type of field found in agriculture
A region around a magnetic material or a moving electric charge within which the force of magnetism acts.
The energy field around a person's body
The force of gravity around a magnet
How is the direction of a magnetic field determined?
By the weight of the magnet
By the direction in which a north pole of a compass needle points in the field
By the color of the magnet
By the temperature of the magnet
Explain the concept of magnetic field lines.
Imaginary lines that represent the shape of a magnet
Lines that indicate the temperature of a magnetic field
Lines that show the path of electric current
Imaginary lines that show the direction and strength of a magnetic field
What are magnetic poles?
Points on a magnet where the magnetic force is the weakest
Regions on a magnet where the magnetic force is the same as the rest of the magnet
Regions on a magnet where the magnetic force is the strongest
Areas on a magnet where the magnetic force is non-existent
What happens when like magnetic poles are brought close to each other?
They repel each other
They attract each other
They explode
They merge into one
Describe the behavior of unlike magnetic poles when brought close to each other.
Create a neutral field
Do not interact at all
Attract each other
Repel each other
What is magnetic induction?
The process by which a material becomes electrically charged when placed in a magnetic field.
The process by which a material changes color when placed in a magnetic field.
The process by which a material becomes magnetized when it is placed in a magnetic field.
The process by which a material loses its magnetism when placed in a magnetic field.
Explain the process of magnetic induction with an example.
When a magnet is moved in and out of a coil of wire, it induces a current in the wire due to magnetic induction.
Magnetic induction is the process of creating a magnetic field by passing an electric current through a wire
Magnetic induction occurs when a non-magnetic material is placed near a magnet
When a magnet is moved closer to a coil of wire, it repels the current in the wire
Name two common magnetic materials and explain their properties.
Copper and aluminum
Iron and steel
Gold and silver
Wood and plastic
How do magnetic materials differ from non-magnetic materials?
Non-magnetic materials are attracted to magnets and can be magnetized.
Magnetic materials have no effect on magnets and cannot be magnetized.
Magnetic materials can be attracted to magnets and can be magnetized.
Magnetic materials repel magnets and cannot be magnetized.
