🧲Magnets have north and south poles that attract and repel each other based on their orientation.
🔍Magnetic fields form closed loops and have a direction associated with them.
🧲Magnetic materials like iron, nickel, and cobalt can be magnetized and attracted by magnets.
⚡️Electromagnets use electricity to generate magnetic fields and can be controlled.
💡Magnetism is a quantum mechanical effect related to the alignment of electron spins.
How do magnets attract and repel each other?
—Magnets have north and south poles. Like poles repel each other, while opposite poles attract.
Which materials can be magnetized?
—Magnetic materials like iron, nickel, and cobalt can be magnetized and attracted by magnets.
Can copper or aluminum be magnetized?
—No, copper and aluminum are not magnetic materials and cannot be magnetized.
How do electromagnets work?
—Electromagnets use electricity to generate a magnetic field. The strength of the magnetic field can be controlled by adjusting the current flow.
What is the quantum mechanical explanation for magnetism?
—Magnetism is a quantum mechanical effect related to the alignment of electron spins in magnetic materials.
