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. Current, field strength, conductor length and angle can each be varied before the magnetic field strength is determined. It fits senior-secondary physics and first-year college labs. Science Lab Supplies in Ambala, India, prices the set for schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each EL4 part, including the five conductor plates, has its own row below. In short, a base plate, coil, acrylic block with pin, adjustment weights and two experimental tracks sit in a foam-lined box with a captive lid, folding handle and bayonet lock, and the set relies on EL1 and EL2 meters and supply.

Applications and Experiments for the EL4 Lorentz Force Set
Each experiment isolates one variable in F = BIL sinθ, so the dependence of the force on current, field, length and angle can be tested before the results are combined 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, after mapping the field of a straight wire on the Magnetic Field Demonstration Device or the Magnetic Field Demo, Round Coil.
- 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. Tell us how many EL4 boxes, and whether the EL1 and EL2+ sets are already in your lab, via the contact page or the enquiry cart; formal bids go through the lab tender page.
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 one variable can be changed at a time and its effect on the Lorentz force seen.
Who supplies the EL4 "Lorentz Force" Electricity Set?
Each EL4 quotation is prepared by Science Lab Supplies in Ambala, India; it lists the contents and points out the EL1 and EL2 accessories that the set depends on.
Is there a teacher's manual?
The set comes with the EL4 student workbook, and its educational literature is supplied in electronic form for easy reproduction. Whether a teacher’s book is added for your order is confirmed on the quotation.
