NEET 2018 Physics Magnetism Questions

Use this page to connect the official 2018 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 bar magnet of magnetic moment 0.40 J T⁻¹ lies in a uniform magnetic field of 0.25 T with its moment parallel to the field. The work required to rotate it slowly so that its moment becomes antiparallel to the field is:

A. 0.10 J
B. 0.31 J
C. zero
D. 0.20 J

Example 2 · difficulty 3/5

The magnetic susceptibility of a paramagnetic material is 3.6 × 10⁻⁵ at 200 K. Assuming Curie's law is obeyed, its susceptibility at 300 K will be:

A. 5.4 × 10⁻⁵
B. 3.6 × 10⁻⁵
C. 8.1 × 10⁻⁵
D. 2.4 × 10⁻⁵

Example 3 · difficulty 1/5

A proton moving horizontally at 2.0×10⁶ m s⁻¹ enters a region where a uniform magnetic field of 0.50 T acts vertically upward, the velocity being perpendicular to the field. Taking the proton charge as 1.6×10⁻¹⁹ C, the magnitude of the instantaneous magnetic force on the proton is:

A. 1.6×10⁻¹³ N
B. 8.0×10⁻¹⁴ N
C. 3.2×10⁻¹³ N
D. zero, because the magnetic force can do no work on the charge

The evidence-first practice loop

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

Frequently asked questions

Are these official NEET 2018 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 2018 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.
