Q: What is the effect of placing a ferromagnetic material in a magnetic field? (2023)
Solution: When a ferromagnetic material is placed in a magnetic field, it becomes magnetized and can retain its magnetism even after the external field is removed.
Steps: 6
Step 1: Understand what a ferromagnetic material is. These are materials like iron, nickel, and cobalt that can be magnetized.
Step 2: Know what a magnetic field is. It is an area around a magnet where magnetic forces can be felt.
Step 3: When a ferromagnetic material is placed in a magnetic field, the magnetic field influences the material's atoms.
Step 4: The atoms in the ferromagnetic material start to align with the direction of the magnetic field.
Step 5: As more atoms align, the material itself becomes magnetized, meaning it starts to act like a magnet.
Step 6: After the external magnetic field is removed, some of the atoms remain aligned, so the material retains its magnetism.
