NEET 2020 Physics Magnetism Questions

Use this page to connect the official 2020 paper with current Physics practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

What to master

magnetic force, fields due to currents, magnetic materials and instruments.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 3/5

A steady current I flows uniformly through the cross-section of a long cylindrical wire of radius R. The ratio of the magnetic field at a point inside the wire at a distance R/2 from the axis to the field at a point outside the wire at a distance 2R from the axis is:

  • A. 1 : 1
  • B. 1 : 2
  • C. 1 : 4
  • D. 2 : 1

Example 2 · difficulty 2/5

Two long straight parallel wires separated by 0.15 m carry steady currents of 5.0 A and 3.0 A in the same sense. Taking μ₀/4π = 10⁻⁷ N A⁻², the magnitude and nature of the force per unit length between them are:

  • A. 2.0×10⁻⁵ N m⁻¹, repulsive
  • B. 6.0×10⁻⁵ N m⁻¹, attractive
  • C. 2.0×10⁻⁵ N m⁻¹, attractive
  • D. 1.0×10⁻⁵ N m⁻¹, repulsive

Example 3 · difficulty 3/5

A rectangular coil of 50 turns, each of area 20 cm², carries a current of 0.20 A and is placed in a uniform magnetic field of 0.50 T. When the plane of the coil lies parallel to the field, the torque experienced by the coil is:

  • A. 2.0×10⁻⁴ N m
  • B. 1.0×10⁻² N m
  • C. zero
  • D. 1.0×10⁻¹ N m

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2020 Physics Magnetism PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2020 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
