The SI unit of current is the ampere, which is defined as the flow of charge in units of <u>coulomb</u> over a period of time measured in <u>seconds.</u>

<h3>What is Current?</h3>
Electrical charge carriers, often electrons or atoms deficient in electrons, travel as current. The capital letter I is a typical way to represent the current. The ampere, denoted by the letter A, is the common unit. An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One coulomb of electrical charge (6.24 x 1018 charge carriers) traveling by a given place in one second is represented by one ampere of current.
Conventional current, also known as Franklin current, is thought by physicists to flow from relatively positive points to comparatively negative locations. The most prevalent charge carriers, electrons, are negatively charged. From somewhat negative to relatively good points, they move.

Answer:
2.5 x 10^-3 T
Explanation:
n = 100 turns / cm = 10000 turns / m, R = 60 ohm, V = 12 V
i = V / R = 12 / 60 = 0.2 A
Magnetic field due to solenoid is
B = μ0 x n x i
B = 4 x 3.14 x 10^-7 x 10000 x 0.2
B = 2.5 x 10^-3 T
