Mnemonic: "Rare Lawn, Beautiful Nature, Green Earth"

Mnemonics: Magnetic Effects of Electric Current | Science Class 10

2. Magnetic Field due to Current through a Circular Loop

Mnemonic: "Larger Loops, Straight Centre"

  • Larger: Circles become larger away from the loop.
  • Straight: Magnetic field appears straight at the center.

3. Fleming's Left-Hand Rule (for motors)

Mnemonic: "Father Made Rice"

  • F = Force (Thumb)
  • M = Magnetic field (Index finger)
  • R = Current (Middle finger)

This helps you remember the directions of Force, Magnetic field, and Current for motor action.

4. Right-Hand Thumb Rule 

Mnemonic: "Grip the Current"

  • Thumb = Direction of Current
  • Fingers = Curl around to show the direction of the Magnetic field

This mnemonic helps you visualize the right-hand thumb rule to determine the direction of the magnetic field.
