Field of Magnets

What are magnetic field lines?

• A type of rope made from magnetic material

• A visual representation of the direction and strength of a magnetic field.

• A type of plant that grows near magnets

• The lines on a map that show where magnets are located

Explain the concept of magnetic force.

• Magnetic force is the force exerted by gravity on magnetic materials.

• Magnetic force is the force exerted by sound waves on magnetic materials.

• Magnetic force is the force exerted by a magnet or a magnetic field on a magnetic material.

• Magnetic force is the force exerted by electricity on magnetic materials.

What are the two types of magnetic poles?

• East pole and West pole

• North pole and South pole

• Positive pole and Negative pole

• Top pole and Bottom pole

How are magnetic field lines formed around a bar magnet?

• Due to the gravitational force acting on the magnet.

• Because of the heat generated by the magnet.

• As a result of the magnet being exposed to sunlight.

• Due to the alignment of magnetic domains within the magnet.

State the direction of magnetic field lines around a current-carrying wire.

• Spiral

• Random

• Circular

• Straight

What is the SI unit of magnetic field strength?

• watt

• ampere

• joule

• tesla

Describe the behavior of like and unlike magnetic poles when brought close to each other.

• Create a neutral field

• Repel or attract

• Merge into a single pole

• Spin around each other

Explain the factors affecting the strength of the magnetic force between two magnets.

• Color, size, and weight

• Distance, orientation, and magnetic properties

• Shape, texture, and material

• Temperature, pressure, and density

What is the difference between a magnetic field and a magnetic force?

• The magnetic field is the area around a magnet where its force is felt, while the magnetic force is the area around a magnetic material where its force is felt.

• The magnetic field is the force exerted by a magnet, while the magnetic force is the area around a magnet where its force is felt.

• The magnetic field is the area around a magnet where its force is felt, while the magnetic force is the force exerted by a magnet on another magnet or a magnetic material.

• The magnetic field is the force exerted by a magnet, while the magnetic force is the force exerted by a magnetic material on a magnet.

How can the direction of a magnetic field be determined using a compass?

• By counting the number of lines on the compass

• By observing the direction in which the compass needle points.

• By measuring the temperature of the compass

• By listening to the sound the compass makes
