Product Specification Sheet
Force on a Conductor in a Magnetic Field – Laplace Law Apparatus
Model Number: MTME-37
The Force on a Conductor in a Magnetic Field – Laplace Law Apparatus is designed to demonstrate the electromagnetic force acting on a current-carrying conductor placed within a magnetic field. Micro Technologies supplies the apparatus with a pair of powerful U-shaped magnets, a brass axle fitted with two plastic discs, two conducting rails, and 4 mm electrical sockets. When current passes through the axle while it lies within the magnetic field, the axle is repelled and rolls along the rails, providing a clear demonstration of Laplace force.
Product Specification
The Force on a Conductor in a Magnetic Field Apparatus provides a direct and highly visible demonstration of the force experienced by an electric current when it passes through a conductor located within a magnetic field.
The apparatus incorporates a pair of powerful magnets arranged in a U-shaped holder. This arrangement produces a magnetic field across the experimental region where the movable conducting axle is positioned.
A brass axle forms the current-carrying conductor in the experiment. The axle is fitted with two plastic discs, allowing it to roll smoothly along the conducting rails while maintaining the required electrical and mechanical arrangement.
Micro Technologies provides two rails positioned between the magnet poles. These rails support the brass axle and also provide an electrical path for supplying current to the movable conductor.
The apparatus incorporates 4 mm electrical sockets for connection to a suitable external power source. When current flows through the rails and brass axle, the conductor experiences an electromagnetic force due to its interaction with the magnetic field.
This force causes the axle to be repelled and roll away from the central magnetic-field region along the rails. The resulting movement provides a clear mechanical indication of the force acting on a current-carrying conductor.
The apparatus can also be used to investigate how the direction of current and orientation of the magnetic field determine the direction of force. Reversing either one can reverse the direction of the resulting electromagnetic force.
The setup provides a practical demonstration of the relationship between electricity, magnetism, and mechanical force, forming an important experimental basis for understanding electromagnetic actuators and electric motor principles.

FAQs
What is the Force on a Conductor in a Magnetic Field apparatus used for?
It is used to demonstrate the electromagnetic force acting on a current-carrying conductor placed within a magnetic field.
What law does the apparatus demonstrate?
The apparatus demonstrates Laplace law, describing the force acting on a current-carrying conductor in a magnetic field.
What type of magnets are provided?
A pair of powerful magnets arranged in a U-shaped holder is provided.
What material is the movable axle made from?
The movable axle is made from brass.
Why are plastic discs fitted to the axle?
Two plastic discs support the axle's rolling movement along the rails while forming part of the mechanical arrangement.
How does the experiment produce motion?
When current passes through the brass axle while it is located in the magnetic field, electromagnetic force acts on the conductor and causes the axle to roll along the rails.
What happens to the axle when current is applied?
The axle is repelled from the central magnetic-field region and rolls away along the rails.
What electrical connections are provided?
The apparatus incorporates 4 mm sockets for connection to a suitable external power source.
Can the direction of force be changed?
Yes. Reversing the direction of current or the magnetic-field orientation reverses the direction of the electromagnetic force.
Does this apparatus demonstrate the motor effect?
Yes. The force acting on the current-carrying conductor is the same fundamental electromagnetic effect used in electric motors.
Is an external power supply required?
Yes. A suitable controlled power source is required to supply current through the rails and axle.
Can Laplace Law Apparatus be supplied in bulk?
Yes. Micro Technologies can supply this apparatus in bulk for laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional procurement.
