Limited Warranty
PASCO scientific warrants this product to be free from defects in materials and workmanship for a period of one year from the date of shipment to the customer. PASCO will repair or replace, at its option, any part of the product which is deemed to be defective in material or workmanship. This warranty does not cover damage to the product caused by abuse or improper use. Determination of whether a product failure is the result of a manufacturing defect or improper use by the customer shall be made solely by PASCO scientific. Responsibility for the return of equipment for warranty repair belongs to the customer. Equipment must be properly packed to prevent damage and shipped postage or freight prepaid. (Damage caused by improper packing of the equipment for return shipment will not be covered by the warranty.) Shipping costs for returning the equipment, after repair, will be paid by PASCO scientific.
Equipment Return
Should the product have to be returned to PASCO scientific for any reason, notify PASCO scientific by letter, phone, or fax BEFORE returning the product.
Upon notification, the return authorization and shipping instructions will be promptly issued.
ä NOTE: NO EQUIPMENT WILL BE ACCEPTED FOR RETURN WITHOUT AN AUTHORIZATION FROM PASCO.
When returning equipment for repair, the units must be packed properly. Carriers will not accept responsibility for damage caused by improper packing. To be certain the unit will not be damaged in shipment, observe the following rules:
The packing carton must be strong enough for the item shipped.
Make certain there are at least two inches of packing material between any point on the apparatus and the inside walls of the carton.
Make certain that the packing material cannot shift in the box or become compressed, allowing the instrument come in contact with the packing carton.

Introduction
A current-carrying wire in a magnetic field experiences a force that is usually referred to as a magnetic force. The magnitude and direction of this force depend on four variables: the magnitude of the current (I); the length of the wire (L); the strength of the magnetic field (B); and the angle between the field and the wire (θ).
This magnetic force can be described mathematically by the vector cross product:
Fm = IL X B,
or in scalar terms,
Fm = ILBsinθ.
With the PASCO SF-8607 Basic Current Balance, you can vary three of the variables in the equation—the current, the length of the wire, and the strength of the magnetic field—and measure the resulting magnetic force. By adding the SF-8608 Current Balance Accessory, you can also vary the angle between the wire and the magnetic field, thereby performing a complete investigation into the interaction between a current carrying wire and a magnetic field.
This manual supplies general operating instructions for both the SF-8607 Basic Current Balance and the SF-8608 Current Balance Accessory. Step-by-step instructions for four experiments are also included.
