Class 12 Physics simulations · Magnetism and Matter

Earth’s magnetic field components

Resolve the field into horizontal and vertical components.

Open the simulation

What to notice

A dip needle follows the total field; a horizontal compass follows its horizontal component.

Key relation

BH = BcosI; BV = BsinI

Try this

Set inclination to 90° and inspect the horizontal component.

What you can change

• Total field: 25 to 65 µT
• Inclination: 0 to 90 °
