Q55RRB JE CBT-1, 19 Feb 2026, Shift 3 (4:30 PM)
A student observes that a compass needle deflects when brought near a current- carrying wire. Using your understanding of magnetic fields, explain why this happens.
  1. AA current-carrying wire creates a magnetic field that exerts a force on the compass needle.
  2. BThe wire causes a gravitational effect moving the needle.
  3. CThe wire heats up, causing air currents to move the needle.
  4. DThe wire produces an electric force that acts on the compass needle.
Show answerHide answer

Correct answer: (A) A current-carrying wire creates a magnetic field that exerts a force on the compass needle.

Q56RRB JE CBT-1, 19 Feb 2026, Shift 3 (4:30 PM)
An electric iron uses a heating element made of an alloy instead of pure metal. Which property of alloys justifies this choice?
  1. AAlloys have higher resistivity and do not oxidise readily at high temperatures
  2. BAlloys are cheaper
  3. CAlloys are better conductors
  4. DAlloys have lower resistivity
Show answerHide answer

Correct answer: (A) Alloys have higher resistivity and do not oxidise readily at high temperatures

  1. AIt becomes twice as large
  2. BIt becomes four times as large
  3. CIt becomes half as large
  4. DIt remains unchanged
Show answerHide answer

Correct answer: (A) It becomes twice as large

Q59RRB JE CBT-1, 19 Feb 2026, Shift 1 (9:00 AM)
If an ammeter reading increases when a thicker wire replaces a thinner one of the same material and length, what is the most likely reason?
  1. AThe wire's resistivity increased
  2. BThe voltage across the wire decreased
  3. CThe wire's length is shorter
  4. DThe resistance of the thicker wire is lower, allowing more current
Show answerHide answer

Correct answer: (D) The resistance of the thicker wire is lower, allowing more current
