Question 1

Easy

Which common metal is most strongly attracted to a magnet?

Source: Iron is the classic magnetic metal — aluminum and copper feel metallic but a magnet ignores them entirely.

Question 2

Easy

What do we call the two ends of a bar magnet?

Source: Every magnet has a north and a south pole — and you can never have just one.

Question 3

Easy

A compass needle naturally settles pointing toward which direction?

Source: The needle aligns with Earth's field, swinging to point roughly north wherever you stand.

Question 4

Easy

Which instrument uses a magnet to help you find your way?

Source: A compass is just a tiny magnet free to spin and line up with the planet.

Question 5

Easy

When two identical poles of magnets are pushed together, they will?

Source: Like poles shove each other away — opposites are the ones that snap together.

Question 6

Easy

Earth itself behaves like one enormous what?

Source: Our spinning molten-iron core turns the whole planet into a giant bar magnet.

Question 7

Easy

Ancient sailors guided ships using a naturally magnetic rock called?

Source: Lodestone is naturally magnetized iron ore — the world's first compass material.

Question 8

Easy

Every magnet is surrounded by an invisible region of force called a magnetic what?

Source: Iron filings reveal the magnetic field's hidden looping lines around any magnet.

Question 9

Easy

Which household device uses magnets to produce sound?

Source: A speaker's magnet pushes a coil back and forth, vibrating the cone to make sound.

Question 10

Easy

If you cut a bar magnet cleanly in half, you end up with?

Source: Slice a magnet and each piece instantly grows its own north and south pole.

Question 11

Medium

Besides iron, which metal is naturally magnetic on its own?

Source: Nickel and cobalt join iron as the everyday metals a magnet can actually grab.

Question 12

Medium

Hospital MRI machines work thanks to an extremely strong what?

Source: MRI uses no X-rays at all — just a magnet so strong it can yank metal across a room.

Question 13

Medium

A compass needle's north end is actually drawn to a magnetic pole that is physically a?

Source: Earth's geographic north is magnetically a south pole — that's why opposite needle ends are attracted.

Question 14

Medium

Maglev trains glide above the track without touching it using what force?

Source: Powerful magnets lift and propel maglev trains, removing wheel friction entirely.

Question 15

Medium

The northern lights appear when Earth's magnetic field funnels what toward the poles?

Source: Charged particles from the Sun follow magnetic lines to the poles, glowing as auroras.

Question 16

Medium

Computer hard drives store your files as billions of tiny what?

Source: A hard drive writes data by flipping microscopic magnetic regions on a spinning disk.

Question 17

Medium

Which migrating animals are thought to navigate using Earth's magnetic field?

Source: Sea turtles sense the field like a built-in GPS, crossing oceans back to their birth beach.

Question 18

Hard

What is the standard scientific unit for magnetic field strength?

Source: The tesla measures magnetic strength — an MRI runs at a couple, a fridge magnet barely a hundredth.

Question 19

Hard

Over millions of years, Earth's magnetic poles occasionally do what?

Source: North and south have swapped hundreds of times — rocks on the seafloor record each flip.

Question 20

Hard

Migratory birds may literally sense magnetic fields using cells in their?

Source: Light-sensitive proteins in birds' eyes may let them actually see Earth's magnetic field.
