Electromagnet Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-11183
The Lab Exports U-Shaped Electromagnet features a solid, high-permeability soft iron core bent into a classic U-shape configuration. This intentional geometric design brings the opposing magnetic poles close together, concentrating the magnetic flux to maximize lifting capacity and field strength during laboratory demonstrations. The core is wrapped with insulated copper wire windings, ensuring optimal electrical conductivity and uniform field distribution.
Engineered explicitly for classroom safety and longevity, the coils are protected by durable outer layers to prevent accidental short circuits or heat damage. Mounted on a stable base with clearly labeled 4mm safety terminals, this instrument integrates seamlessly with standard laboratory power supplies and rheostats. It serves as an essential tool for hands-on physics experiments, bridging the gap between theoretical textbook equations and physical reality.
Key Features
High-Permeability Iron Core: Soft iron material ensures rapid magnetization when energized and minimal residual magnetism when disconnected.
Optimized Winding Capacity: Heavy-gauge insulated copper wire provides reliable resistance and strong magnetic field generation.
Concentrated Magnetic Flux: U-shaped design aligns north and south poles parallel to each other for lifting power demonstrations.
Robust Lab Terminals: Equipped with standard 4mm binding posts for quick, secure connections to standard physics laboratory instruments.
Durable Build Quality: Protective bobbin coverings insulate the copper coils against wear and continuous classroom handling.

1 x Soft iron armature (keeper bar) with integrated hook
1 x Product instructional manual and experimental guide
Applications / Uses
Demonstrating the relationship between electric current and magnetic field strength in science classrooms.
Conducting qualitative lifting experiments using the included soft iron armature and slotted mass sets.
Exploring the differences between temporary electromagnets and permanent magnets.
Investigating how variations in voltage and current affect electromagnetic force.
How to Use the U-Shaped Electromagnet
Securely mount or place the U-shaped electromagnet on a flat, stable laboratory workbench.
Connect the 4mm terminal binding posts to a variable DC power supply using insulated banana plug patch cords.
Set the DC power supply voltage to 0V before switching the unit on.
Slowly increase the voltage to the recommended 4-6V DC range, keeping track of the current reading.
Place the soft iron armature across the two exposed poles to test the magnetic attraction and lifting power.
Turn off the power supply immediately after data collection to prevent the coils from overheating.
Safety Note: Never exceed the maximum current rating of 2 Amperes. The coils will generate heat during prolonged operation; limit continuous activation to short intervals to ensure user safety and equipment longevity.
Care & Maintenance
Store the instrument in a clean, dry environment away from corrosive chemicals or excessive moisture to prevent iron core oxidation.
Wipe the metal pole pieces with a dry, lint-free cloth after use; apply a micro-layer of light machine oil if storing long-term.
Inspect the wire insulation regularly to ensure no copper is exposed or frayed.

Frequently Asked Questions
What is a U-shaped electromagnet used for?
A U-shaped electromagnet is primarily used in physics classrooms to demonstrate electromagnetism, magnetic flux concentration, and how an electrical current generates a temporary magnetic force field.
Can this electromagnet be run on AC power?
No, this electromagnet is designed to operate on low-voltage DC power. Running it on AC power will cause rapid pole switching, excessive vibration, and immediate overheating of the core.
What happens when you turn off the current?
When the DC power supply is turned off, the current stops flowing and the soft iron core rapidly demagnetizes, causing it to lose its lifting power and drop the armature.
Is this instrument safe for middle school students?
Yes, because it operates effectively at low voltages (4-6V DC), it is perfectly safe for middle school and high school science environments when used under proper instructor supervision.
Why does it use a soft iron core instead of steel?
Soft iron is selected because it has high magnetic permeability and low retentivity. This allows it to magnetize intensely when current flows and demagnetize completely when the current is switched off, unlike steel which retains permanent magnetism.
