Q & A

What is the main objective of this experiment?

The main objective of this experiment is to understand and measure the magnetic field inside a solenoid and its relationship with the electric current flowing through it.

What equipment is required for this experiment?

The experiment requires a power supply (6V), a solenoid (50 cm), a rheostat, connecting cables, a magnetic field sensor, a EuroLab interface, and a digital multimeter.

How do you connect the components in this experiment?

First, connect the power supply to the rheostat, then connect the rheostat to the solenoid in a series circuit. The magnetic field sensor is connected to the EuroLab interface, which is then linked to a computer.

What is the role of the rheostat in this experiment?

The rheostat is used to regulate the electric current flowing through the solenoid, allowing you to vary the current during the experiment.

What should be the position of the magnetic field sensor in the solenoid?

The magnetic field sensor should be placed at the center of the solenoid to accurately measure the magnetic field strength.

How should the length of the solenoid be adjusted during the experiment?

The solenoid should be adjusted to 50 cm and the spacing between the coils should be set to ensure a homogeneous magnetic field.

What is the formula used to calculate the slope of the magnetic field vs current graph?

The slope of the graph is calculated using the formula: (y2 - y1) / (x2 - x1), where y2 and y1 represent the magnetic field values (B2 and B1), and x2 and x1 represent the corresponding current values (I2 and I1).

How is the permeability constant (μ₀) determined from the graph?

The permeability constant (μ₀) is calculated by dividing the slope of the magnetic field vs current graph by the number of turns per unit length of the solenoid.

What is the relationship between the magnetic field and the current in the solenoid?

The magnetic field strength inside a solenoid is directly proportional to the current flowing through it. As the current increases, the magnetic field strength also increases.

How do you compare the permeability constants obtained from two experiments?

The permeability constant from two experiments can be compared by calculating the relative deviation using the formula: K = μ₀ from the first experiment divided by the μ₀ from the second experiment, where μ₀ represents the permeability constant.
