WebNov 17, 2010 · Factors affecting magnetic force on a current-carrying conductor in a magnetic field: Strength of the magnetic field. Current flowing through the wire. Length of the wire. F = BI lsinθ F = B I l s i n θ, where. F is force acting on a current carrying conductor,B is magnetic flux density (magnetic field strength),
Webtemperatures and number of current-carrying conductors. Ampacity ratings need to be derated if more than three current-carrying conductors are in a raceway or cable according to the requirements in NEC 2014 Article 310. More current-carrying conductors in an enclosed space may result in a greater ambient temperature. The ampacity of those WebSpecified here, 2 Single Core 2.5mm^2 PVC insulated cables have a current carrying capacity of 24 Amps (AC/DC) with the conductor operational temperature at 70ºC and an ambient temperature of 30ºC. …
WebThe magnetic force on a current-carrying wire in a magnetic field is given by F → = I l → × B →. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sin θ = 1.
