NCERT lines NEET asked again and again

Read these lines from your NCERT book twice: NEET has built questions on each of them more than once.

Inside a solid wire the field grows linearly with r , peaks at the surface, then falls as 1/r outside. A hollow pipe has no field inside.
AIPMT 1999NEET 2022
The magnetic force is always perpendicular to velocity , so it changes only direction. A charge in B keeps its speed and kinetic energy constant.
AIPMT 2003AIPMT 2008
For v⊥B the charge moves in a circle of r = mv/qB . At equal momentum, radius goes as 1/q ; at equal kinetic energy as √m/q.
NEET 2015NEET 2019
Parallel wires with currents in the same direction attract . The force per unit length is μ₀ I₁ I₂/2πd , equal on both wires.
