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. 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 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.
