Magnetic Fields and Compasses

How does a plotting compass differ from a regular compass?

• It aligns with the magnetic field of a magnet

• It aligns with the geographic North Pole

• It is larger in size

• It does not align with any magnetic field

What is the function of a plotting compass when placed near a bar magnet?

• It aligns with the Earth's magnetic field

• It aligns with the magnetic field of the magnet

• It measures the temperature gradient

• It shows the direction of wind flow

What is the significance of the Earth's geographic North Pole?

• It is the same as the magnetic North Pole

• It is located in the Southern Hemisphere

• It marks the top of the Earth's axis

• It has no significance in navigation

What is the direction of magnetic field lines from the north pole to the south pole?

• South to north

• East to west

• North to south

• West to east

What determines the strength of a magnetic field in the context of magnetic field lines?

• The color of the lines

• The spacing between the lines

• The shape of the lines

• The presence of ferrofluid

How is a compass needle affected by the Earth's magnetic field?

• It rotates freely in any direction

• It aligns with the magnetic South Pole

• It points towards the magnetic North Pole

• It remains stationary

How do scientists represent the direction of magnetic field lines?

• They always point towards the geographic North Pole

• They always point towards the geographic South Pole

• They always point towards the magnetic South Pole

• They represent the direction of the force exerted on a magnetic material

What role do iron filings play in visualizing magnetic field patterns?

• They become permanently magnetized

• They repel each other

• They show the shape of the magnetic field

• They align with the Earth's magnetic field

Where does a compass needle point towards?

• Geographic South Pole

• Magnetic South Pole

• Magnetic North Pole

• Equator

What is the role of a plotting compass in visualizing a magnetic field?

• It aligns with the Earth's magnetic field

• It points towards the geographic North Pole

• It aligns with the magnetic field of a bar magnet

• It shows the exact coordinates of magnetic anomalies
