  • Q1 · Magnetic Effects & Materials · MEDIUM

    A charged particle of mass m and charge q enters a region of uniform magnetic field B perpendicular to its velocity v. If the particle exits the field region after tracing a quarter circle, the time spent in the field is:

  • Q2 · Magnetic Effects & Materials · MEDIUM

    A proton moving with velocity v enters a region of uniform magnetic field B perpendicular to its velocity. If the proton completes a semicircle of radius r inside the field region, the time spent inside the field is:

  • Q3 · Magnetic Effects & Materials · EASY

    A circular coil of radius 10 cm carries a current of 2 A. The magnetic field at its center is approximately: (μ₀ = 4π × 10⁻⁷ T·m/A)
