| 2 | ⚡ FORCE ON A CURRENT-CARRYING CONDUCTOR — QUICK NOTES
🔹 Magnetic Force on a Current-Carrying Conductor
A current-carrying conductor placed in a magnetic field experiences a force.
Formula:
F = BIL sinθ
where,
F = Magnetic Force
B = Magnetic Field
I = Current
L = Length of the Conductor
θ = Angle between the conductor and the magnetic field
🔹 Special Cases
• θ = 0° or 180°
F = 0
(Conductor parallel to the magnetic field)
• θ = 90°
F = BIL
(Maximum Force)
🔹 Direction of Force
Determined by Fleming's Left-Hand Rule
First Finger → Magnetic Field (B)
Second Finger → Current (I)
Thumb → Force (F)
🔹 Force Between Two Parallel Current-Carrying Conductors
F/L = μ₀I₁I₂/2πd
where,
I₁, I₂ = Currents in the Conductors
d = Distance Between the
Conductors
🔹 Torque on a Current Loop
τ = NIAB sinθ
where,
N = Number of Turns
A = Area of the Loop
🔹 Magnetic Dipole Moment
M = NIA
🔹 Torque on a Magnetic Dipole
τ = MB sinθ
⚡ OLYMPIAD FACTS
✓ A conductor experiences maximum force when it is perpendicular to the magnetic field.
✓ No force acts when the conductor is parallel to the magnetic field.
✓ Parallel currents in the same direction attract each other.
✓ Parallel currents in opposite directions repel each other.
✓ The SI unit of magnetic field is tesla (T).
🎯 MUST REMEMBER
F = BIL sinθ
F_max = BIL
F/L = μ₀I₁I₂/2πd
τ = NIAB sinθ
M = NIA
τ = MB sinθ | 906 |

| 6 | A glass cube of refractive index 1.5 and edge length 1 cm contains a tiny black spot at its centre. A circular opaque sheet is placed symmetrically on its upper surface so that the spot cannot be seen from above.
The minimum radius of the sheet is: | 1 235 |
| 7 | Choose the incorrect statement: | 1 134 |
| 8 | 🌈 REFRACTION & TOTAL INTERNAL REFLECTION — FORMULA SHEET
🔹 Refractive Index
n = c/v
where,
n = Refractive Index
c = Speed of Light in Vacuum
v = Speed of Light in the Medium
🔹 Relative Refractive Index
n₂₁ = n₂/n₁ = v₁/v₂
🔹 Snell's Law
n₁ sin i = n₂ sin r
🔹 Critical Angle
sin C = n₂/n₁
(for n₁ > n₂)
🔹 Condition for Total Internal Reflection (TIR)
1. Light must travel from a denser medium to a rarer medium.
2. Angle of incidence must be greater than the critical angle.
🔹 Apparent Depth
Apparent Depth = Real Depth/n
🔹 Real Depth
Real Depth = n × Apparent Depth
🔹 Lateral Shift (Parallel Slab)
d = t × sin(i − r)/cos r
where,
t = Thickness of Slab
🔹 Optical Path Length
OPL = nd
🔹 Speed of Light in a Medium
v = c/n
⚡ OLYMPIAD FACTS
✓ The frequency of light remains unchanged during refraction.
✓ The wavelength changes when light enters a different medium.
✓ Total Internal Reflection occurs only when light travels from a denser medium to a rarer medium.
✓ A diamond sparkles due to repeated Total Internal Reflection.
✓ Optical fibres work on the principle of Total Internal Reflection.
🎯 MUST REMEMBER
• n = c/v
• n₂₁ = n₂/n₁ = v₁/v₂
• n₁ sin i = n₂ sin r
• sin C = n₂/n₁
• Apparent Depth = Real Depth/n
• Real Depth = n × Apparent Depth
• d = t × sin(i − r)/cos r
• OPL = nd
• v = c/n
