The magnetic field (B) at a distance r from a straight current-carrying conductor is given by B = μ₀I/2πr.

The magnetic field (B) around a straight current-carrying conductor is inversely proportional to the distance (r) from the wire, given by B ∝ 1/r.

The magnetic field (B) inside a long solenoid is given by B = μ₀nI, where n is the number of turns per unit length and I is the current.

The magnetic field lines around a straight current-carrying conductor form concentric circles centered around the wire.

The magnetic field lines around a straight current-carrying conductor form concentric circles centered around the wire.

The magnetic field lines inside a bar magnet are directed from the North pole to the South pole.

The maximum displacement is defined as the amplitude.

Maximum speed (v_max) = ωA => ω = v_max / A = 4 m/s / 2 m = 2 rad/s.

Electromagnetic induction was discovered by Michael Faraday.

The potential energy (U) stored in a capacitor is given by U = 1/2 CV^2, which shows it is directly proportional to both charge and voltage.

The potential energy (U) stored in a capacitor is given by U = 1/2 CV^2.

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.

According to Gay-Lussac's law, the pressure of an ideal gas is directly proportional to its temperature when the volume is held constant.

This relationship is known as Boyle's Law, which states that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.

The restoring force (F) is directly proportional to the displacement (x) and acts in the opposite direction, F = -kx.

The restoring force (F) is directly proportional to the displacement (x) and acts in the opposite direction, F = -kx.

Restoring force (F) is proportional to displacement (x), F = -kx.

The self-inductance of a coil depends on the number of turns, area of cross-section, and length of the coil.

The specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of the substance by 1°C.

The specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kg of the substance by 1 degree Celsius.

Uncertainty is often defined as the range of values within which the true value lies.

Joule is the SI unit of energy, which is also equivalent to work done.

The unit of force (Newton) is derived from mass, length, and time: kg·m/s².

The SI unit of force is the Newton (N).

The SI unit of power is defined as Joule per second (Watt).

The SI unit of power is the Watt (W).

Power is defined as Joule per second (Watt).

One joule is defined as one newton meter (N·m).

Viscosity measures a fluid's resistance to flow; higher viscosity means the fluid flows less easily.

The work done by an ideal gas during an isothermal expansion is given by W = nRT ln(Vf/Vi), where Vf and Vi are the final and initial volumes.
