Unformatted text preview: ircuit shown below uses two identical springs to support a W=10cm long horizontal wire with a mass of 5 g. A current is driven through the wire by a 12-Volt battery and a resistor . In the absence of a magnetic field, the weight of the wire causes the springs to stretch a distance of 0.2 cm each. When a uniform magnetic field B is applied (normal to the page), the strings are observed to stretch by an additional 0.5 cm. What is the intensity of the magnetic flux density B?
