Ampere's Law states ∮B·dl = μ₀I_enc, where I_enc is the enclosed current.

Ampere's Law states that the line integral of the magnetic field B around a closed path is equal to μ₀ times the total current I enclosed by the path.

Ampere's Law states that the line integral of B around a closed loop is μ₀ times the total current through the loop.

Inside a long straight conductor, the magnetic field is zero because the contributions from all parts of the conductor cancel out.

According to Ampere's Law, the line integral of the magnetic field around a closed loop equals μ₀ times the total current enclosed by the loop.

Using Ampere's Law, B = μ₀I/2πR for points outside the cylindrical conductor.

For points outside the cylinder, B = μ₀I/2πr.

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

Using Ampere's Law, B = μ₀nI where n is the number of turns per unit length.

The magnetic field inside a toroid is given by B = μ₀NI/2πR.

Using Ampere's Law, B = μ₀I/2R at the center of a circular loop.

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

According to Ampere's Law, the magnetic field B at a distance r from a long straight conductor carrying current I is given by B = μ₀I/(2πr).

According to Ampere's Law, the magnetic field B around a long straight conductor is given by B = μ₀I/(2πr).

Using Ampere's Law, the magnetic field B at a distance r from a long straight wire carrying current I is given by B = μ₀I/(2πr).

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

Using the formula F = BIL, where B is the magnetic field, I is the current, and L is the length of the wire (1 m), F = 0.1 T * 5 A * 1 m = 0.5 N.

Using Ampere's Law, B = μ₀I/2πr, where μ₀ = 4π × 10^-7 Tm/A, we find B = (4π × 10^-7)(5)/(2π(0.1)) = 0.1 T.

The magnetic field at the center of a loop is directly proportional to the current.

The magnetic field at the center of a circular loop is directly proportional to the current; thus, if the current is doubled, the magnetic field also doubles.

The magnetic field is directly proportional to the current, so it doubles.

According to Ampere's Law, the magnetic field is directly proportional to the current, so doubling the current will double the magnetic field.

Reversing the current in a wire reverses the direction of the magnetic field around it.

If the magnetic field around a closed loop is constant, the current through the loop must also be constant according to Ampere's Law.

The magnetic field at the center of a circular loop is inversely proportional to the radius; thus, doubling the radius halves the magnetic field.

The magnetic field at the center of a circular loop is given by B = (μ₀I)/(2r). If the radius is doubled, the magnetic field strength is halved.

The magnetic field at the center is inversely proportional to the radius, so it quadruples.

Two parallel wires carrying currents in the same direction will attract each other due to the magnetic fields they produce.

The line integral of B around the path is equal to μ₀I by Ampere's Law.

According to Ampere's Law, if the net current through a closed loop is zero, the line integral of the magnetic field around that loop is also zero, but the magnetic field can still be non-zero in some regions.
