What does the Right-Hand Thumb Rule indicate?
💡 Hint: Think about your thumb's orientation.
True or False: Magnetic field strength increases as you move further away from the wire.

Challenge Problems
Push your limits with advanced challenges
If a straight wire carries a current of 3 A and the magnetic field strength at a distance of 2 cm is measured, what will be the magnetic field strength at a distance of 4 cm if the current remains constant? Assume linearity.
💡 Hint: Refer back to the concept of distance influencing field strength.
A wire carrying 4 A produces a magnetic field with a strength of 0.2 T at a distance of 5 cm. If the current is doubled, what will the new strength of the magnetic field be at the same distance?
💡 Hint: Think about how current influences the intensity of the magnetic field.
