EL4 "Lorentz Force" Electricity Set
Product Code : SCL-PL-12307
EL4 "Lorentz Force" Electricity Set (SKU SCL-PL-12307) is a focused set for six quantitative experiments on the force acting on a current-carrying conductor in a magnetic field. Students vary current, field strength, conductor length and angle, and finally determine the magnetic field strength. It fits senior-secondary physics and first-year college labs. Science Lab Supplies offers the set from Ambala, India, to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The parts are stored in a box with a captive lid and folding handle, in a foam insert with pre-formed cavities. A bayonet lock lets several boxes stack securely for one-hand carrying. The key difference from the other EL sets is its set of conductor plates of different lengths and angles.

Applications and Experiments for the EL4 Lorentz Force Set
Each experiment isolates one variable in F = BIL sinθ, so students can test how the force depends on current, field, length and angle before combining the results to measure field strength. This makes the set a natural follow-on to the EL1 and EL2+ boxes, whose meters and power supply it uses.
- Class 12 physics (moving charges and magnetism): force on a current-carrying conductor.
- Lorentz force versus current and versus magnetic field strength.
- Lorentz force versus conductor length, using the 25, 35 and 50 plates.
- Lorentz force versus the angle between field and current, using the 90°, 75° and 65° plates.
- B.Sc. first-year practical: determining magnetic field strength.
Standard Scope of Supply
The box contains the base plate, five conductor plates, coil, acrylic block with pin, adjustment weights, tweezers, two experimental tracks and the EL4 workbook. The set will not work without the multimeters, battery and power supply supplied with the EL1 and EL2 sets, so order those too if you do not already have them.
Packing, MOQ and Lead Time
A quotation can be raised for one EL4 box or for a batch matching your lab groups, and it states packing, delivery time and price for that quantity. If you need the EL1 and EL2+ sets for their meters and power supply, they can be itemised on the same quotation.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter and can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Use the contact page to ask a question, the enquiry cart to list several sets, and the lab tender page for tenders.
Frequently Asked Questions
Can the EL4 set be used on its own?
No. It needs the multimeters, battery and power supply supplied with the EL1 and EL2 sets. Without these accessories the experiments cannot be run.
Why are there five conductor plates?
The plates differ in length (25, 35 and 50) and angle (90°, 75° and 65°), so students can change one variable at a time and see its effect on the Lorentz force.
Who supplies the EL4 "Lorentz Force" Electricity Set?
It is supplied by Science Lab Supplies from Ambala, India; each quotation lists the contents and flags the EL1 and EL2 accessories the set depends on.
Is there a teacher's manual?
The literature listed for this set is the EL4 student workbook, and the EL manuals are supplied in electronic form for easy reproduction.
