Electromagnet design Definition and 19 Threads

Hello, I am trying to develop a magnetic equivalent circuit for a UU-core inductor with two parallel bus bars in the middle of the slot. I am not sure as to how to model the MMF in such problem. The logical way in my mind is to have two current sources to represent the fields of each bus bar...

I am trying to design an electromagnet which consists of a copper PVC sheathed wire wound around a cylindrical plastic spool of Circumference (C) = pi x diameter. The spool has a hollow body of diameter D1. This wire has maximum length (L), cross sectional area A, resistivity P. The spool once...

Hello, I'm trying to make an electromagnetic shaker but I'm not sure if this is possible? Basically I want to wrap an iron core with a solenoid and use AC to shake a magnet at some distance away. I'm not certain on the approach at the moment but I'm kind of looking at the feasibility at the moment.

Hello Everybody, Can somebody help me to find out about Electromagnets and Electric motors? I hope that here it is possible to get an expert opinion about the next question. How strong should be electromagnet to elevate and hold f.e. 1 kg weight in the middle of a ferrous environment (f.e. cube...

Good day I've been the task of designing an electromagnet to remove ferrous material from ore mixture. I've calculated the flux density require to remove the particle from underneath a burden depth of 400mm; which is 792.7177 Gauss. (Force index is: 1.5710*10^6 G^2/m) However what I've been...

Preface: I'm a chemical engineering undergraduate student but as small-time and noob electrical engineering hobbyist. I really only have minimal experience in circuitry and the like. I want to build a series of electromagnets with a variable their strength in order to levitate an opposing...

Hi all, First post, be gentle... I'm trying to build a system based on the MIT Actuated Workbench. They used electromagnets with the following spec: 1.9cm (0.75”) diameter x 3.8cm (1.5”) length, wound with 32-gauge copper wire with a total length resistance of 120-122 ohms, with no metal...

Hello. I am trying to design an EI-core electromagnet (think two c-shaped cores with their gaps abutting). The coils would go on the top and bottom legs of the E (legs B and C in my sketch). There is a sketchbelow and you can find one here...

Hi guys and gals Long story short I'm trying to make an magnetic levitator (like you can see on youtube), basically a floating metal ball, this will be part of a project I'm doing but the issue is I have absolutely no idea how to go about designing a electromagnet from scratch (which is a...

Dear all, I need realizing an electromagnet producing a magnetic field changing in direction with a given frequency (from 100 to 800kHz). Max intensity should be 400-500 Oe. I need applying this magnetic field in a small region (10x 10 mm2) and I would prefer the electromagnet not so big...

guys, I want to design a electromagnet. but i do not know how to start. so could you please tell me what knowledge is needed for electromagnet design? Or you can recommed some data that i can find and buy myself. thanks in advance!

Homework Statement Hi all, I am working on an electromagnet design. It is a C-shape with an air gap of 80mm. The number of coil windings is 320 turns. I would like to generate let's say B = 30 mT = 300 gauss in the air gap. Area of air gap Ag = 80mmX80mm = 6.4e-3. Mean length lg of...

G’day everyone I need some direction / advice in the area of electromagnet design. Application and restrictions: DC supply Push down and hold with 100N of force Pull up with 100N of force and hold with 1,000N of force (or pull up and hold with 1,000N of force) Stroke length: 10mm...

Hey guys, so I have a couple questions about electromagnets that I was hoping to get some insight on here. Basically, I've been tasked with designing an electromagnet that is low-heat (<150F or so) yet high pull force. I'm improving on a past design where the electromagnet got way too hot (>...

Hello Everyone. I'm very new to this website and am turning to anyone for help. I'm trying to design and build a large electromagnet to do some scrap metal lifting for me and my grandpa that can be hooked onto a crane/loader of a tractor/payloader. I'm currently studying electrical and...

Hi everybody, I just had 100m of copper winding wire arrive in the mail so I can build an electromagnet. I'm aiming to pull a 5kg weight along, which is already floating on a separate magnetic field so all friction is removed except air resistance. What I want to do is put an...

I am trying to design a very powerful electromagnet for experimental reasons. However, I am wondering at his absurd sounding conclusion I arrived at! The governing equation of the magnetic field generated by a solenoidal electromagnet is B = u0nI Provided that I keep these things constant 1...

I was trying to get the numbers to design a 1T solenoidal electromagnet with a core of permeability >1000 (electric steel or Permalloy). I think the permeability saturates at some field strength(0.2T?). But I am not sure how to use the formula after saturation. should I just use u0 instead of...

I have magnet wire and I have steel with extremely high iron content. I was just wondering, if I were using the same amount of wire and metal no matter how I built it and I were just making a straight cylindrical electromagnet, what would be the more powerful design? More towards the short and...
