| 6 | ⚡ FORCE ON A MOVING CHARGE — QUICK NOTES
🔹 Magnetic Force on a Moving Charge
A charged particle moving in a magnetic field experiences a force given by:
F = qvB sinθ
where,
F = Magnetic Force
q = Charge
v = Velocity of the Particle
B = Magnetic Field
θ = Angle between v and B
🔹 Special Cases
• θ = 0° or 180°
F = 0
(Motion parallel or antiparallel to the magnetic field)
• θ = 90°
F = qvB (Maximum)
(Motion perpendicular to the magnetic field)
🔹 Direction of Magnetic Force
Use Fleming's Left-Hand Rule (for current) or the Right-Hand Rule for a moving positive charge.
For a negative charge, the force is opposite to the direction obtained for a positive charge.
🔹 Circular Motion in a Magnetic Field
Radius of Circular Path:
r = mv/qB
🔹 Time Period
T = 2πm/qB
🔹 Cyclotron Frequency
f = qB/2πm
🔹 Angular Frequency
ω = qB/m
⚡ OLYMPIAD FACTS
✓ Magnetic force is always perpendicular to both the velocity and the magnetic field.
✓ A magnetic field changes only the direction of motion, not the speed of a charged particle.
✓ A stationary charge experiences no magnetic force.
✓ Magnetic force does no work on a charged particle.
✓ A charged particle moves in a circular path if its velocity is perpendicular to the magnetic field.
🎯 MUST REMEMBER
F = qvB sinθ
F_max = qvB
r = mv/qB
T = 2πm/qB
f = qB/2πm
ω = qB/m | 1 277 |
| 7 | A current I flows through an infinitely long thin-walled cylindrical conductor. The magnetic field at any point inside the conductor is: | 1 129 |
| 8 | A long straight wire of radius a carries a steady current I, uniformly distributed across its cross-section. The ratio of the magnetic field at a distance a/2 and 2a from the axis of the wire is | 1 153 |
| 9 | ⚡ AMPERE'S CIRCUITAL LAW — QUICK NOTES
🔹 Ampere's Circuital Law
The line integral of the magnetic field around any closed path is equal to μ₀ times the net current enclosed by the path.
Formula:
∮B·dl = μ₀Iₑₙc
where,
B = Magnetic Field
dl = Infinitesimal Length Element
Iₑₙc = Net Current Enclosed
μ₀ = Permeability of Free Space
🔹 Magnetic Field Due to a Long Straight Wire
B = μ₀I/2πr
🔹 Magnetic Field Inside a Long Solenoid
B = μ₀nI
where,
n = Number of Turns per Unit Length
🔹 Magnetic Field Inside a Toroid
B = μ₀NI/2πr
where,
N = Total Number of Turns
r = Mean Radius of the Toroid
🔹 Magnetic Field Outside a Long Solenoid
B ≈ 0
🔹 Magnetic Field Outside an Ideal Toroid
B = 0
⚡ OLYMPIAD FACTS
✓ Ampere's Circuital Law is applicable to highly symmetric current distributions.
✓ The magnetic field inside a long solenoid is nearly uniform.
✓ The magnetic field outside an ideal solenoid is approximately zero.
✓ The magnetic field outside an ideal toroid is zero.
✓ The direction of the magnetic field is determined by the Right-Hand Thumb Rule.
🎯 MUST REMEMBER
∮B·dl = μ₀Iₑₙc
B = μ₀I/2πr
B = μ₀nI
B = μ₀NI/2πr
B ≈ 0 (Outside Long Solenoid)
B = 0 (Outside Ideal Toroid) | 1 189 |

| 13 | ⚡ BIOT–SAVART LAW — QUICK NOTES
🔹 Biot–Savart Law
The magnetic field due to a small current element is directly proportional to the current, the length of the current element, and sinθ, and inversely proportional to the square of the distance from the element.
Formula:
dB = (μ₀/4π) (I dl sinθ)/r²
where,
dB = Magnetic Field due to Current Element
I = Current
dl = Current Element
r = Distance from the Element
θ = Angle between dl and r
🔹 Magnetic Field Due to a Long Straight Wire
B = μ₀I/2πr
🔹 Magnetic Field at the Centre of a Circular Loop
B = μ₀I/2R
🔹 Magnetic Field on the Axis of a Circular Loop
B = μ₀IR²/[2(R² + x²)³ᐟ²]
where,
x = Distance from the Centre Along the Axis
🔹 Magnetic Field Due to N Turns
B = μ₀NI/2R
🔹 Magnetic Field Inside a Long Solenoid
B = μ₀nI
where,
n = Number of Turns per Unit Length
🔹 Magnetic Field Inside a Toroid
B = μ₀NI/2πr
⚡ OLYMPIAD FACTS
✓ Biot–Savart Law is used to calculate the magnetic field produced by a current-carrying conductor.
✓ The direction of the magnetic field is given by the Right-Hand Thumb Rule.
✓ The magnetic field is maximum at the centre of a circular loop.
✓ The magnetic field at the centre of a complete circular loop is twice that of a long straight wire at the same distance (R).
✓ Magnetic field is directly proportional to current and inversely proportional to distance.
🎯 MUST REMEMBER
dB = (μ₀/4π)(I dl sinθ)/r²
B = μ₀I/2πr
B = μ₀I/2R
B = μ₀NI/2R
B = μ₀nI
B = μ₀NI/2πr
These are the most frequently used Biot–Savart Law formulas in Olympiad, JEE, and NEET problems. | 1 352 |
