According to Ampere's law, the magnetic field inside a hollow conductor carrying current is zero.

Inside a hollow cylindrical shell, the magnetic field is zero.

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

The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid.

The magnetic field inside a long solenoid is given by B = μ₀nI.

Using Ampere's Law, B = μ₀I/2πr for a long straight conductor.

Using Ampere's Law, B = μ₀I/2πr for a long straight conductor.

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

The magnetic field inside a long, ideal solenoid is uniform and parallel to the axis of the solenoid.

The magnetic field inside a long, ideal solenoid is uniform and parallel.

The magnetic field inside a long, straight solenoid is given by B = μ₀nI, where n is the number of turns per unit length and μ₀ is the permeability of free space.

The magnetic field inside a long, straight solenoid is uniform and parallel to the axis of the solenoid, given by B = μ₀nI, where n is the number of turns per unit length.

The magnetic field inside a long solenoid is given by B = μ₀nI.

The magnetic field at the center of a square loop is given by B = (μ₀I)/(√2a).

The magnetic quantum number (m_l) for a 3d orbital can be -2, -1, 0, 1, or 2.

Magnification m = -v/u = -(-10)/20 = 0.5.

Magnification (m) = -v/u = -(-5)/(-15) = 1/3. Therefore, the magnification is 3.

Magnification (m) = v/u. For an object at 2f, the image distance v = 2f, so m = 2f/(2f) = 1.

Magnification (m) = image distance/object distance = 30/15 = 2.

Magnification (m) = image distance/object distance = 45/15 = 3.

Magnification (m) = -v/u = -10/20 = 0.5, but since we consider absolute value, m = 2.

Magnification (m) = -v/u = -50/25 = -2. The absolute value indicates the image is twice the size of the object.

Magnitude = √(2^2 + (-3)^2 + 6^2) = √(4 + 9 + 36) = √49 = 7.

Magnitude = √(3^2 + 4^2) = √(9 + 16) = √25 = 5

Magnitude |C| = √(6^2 + 8^2 + 10^2) = √(36 + 64 + 100) = √200 = 10√2.

Magnitude of v = √(3^2 + (-4)^2) = √(9 + 16) = √25 = 5.

Most antacids contain a combination of calcium carbonate, magnesium hydroxide, and aluminum hydroxide to neutralize stomach acid.

A potentiometer provides more accurate measurements because it measures voltage by balancing rather than drawing current from the circuit.

The Wheatstone bridge is known for providing high accuracy in measuring unknown resistances.
