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.
