Magnetic Field and Field Lines
Physics ⇒ Electricity and Magnetism
Magnetic Field and Field Lines starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Magnetic Field and Field Lines.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A bar magnet is cut into two equal pieces. What happens to the magnetic field lines?
A solenoid is connected to a battery. What will happen to the magnetic field inside the solenoid if the current is doubled?
A student increases the number of turns in a solenoid while keeping the current constant. What effect does this have on the magnetic field inside the solenoid?
A student observes that iron filings arrange themselves in a pattern around a bar magnet. What does this pattern represent?
A student places a compass near a wire carrying current. The compass needle deflects. What does this indicate about the space around the wire?
Describe what happens to a compass needle when placed near a bar magnet.
Describe what happens to the magnetic field lines when two like poles of two bar magnets are brought close to each other.
Explain why two magnetic field lines never intersect each other.
State one difference between electric field lines and magnetic field lines.
What happens to the strength of the magnetic field as you move farther from a magnet?
What is a magnetic field?
What is the direction of the magnetic field at the center of a circular loop carrying current in the clockwise direction when viewed from above?
