For an assembled accelerometer; direct measurement of magnetic field strength is not a feasible option; as the magnetometer probe cannot be laid inside the micro-space of the sensor. This paper proposed an indirect measurement method of the remnant magnetization of Micro-Pendulum Accelerometer. The measurement is based on the working principle of the accelerometer; using the current output at several different scenarios to resolve the remnant magnetization of the permanent magnet. Iterative Least Squares algorithm was used for the adjustment of the data due to nonlinearity of this problem. The calculated remnant magnetization was  1.035 T. Compared to the true value; the error was less than 0.001 T. The proposed method provides an effective theoretical guidance for measuring the magnetic field of the Wire Suspended Micro-Pendulum Accelerometer; correcting the scale factor and temperature influence coefficients; etc.<\/jats:p>","DOI":"10.3390\/s150408527","type":"journal-article","created":{"date-parts":[[2015,4,14]],"date-time":"2015-04-14T03:11:46Z","timestamp":1428981106000},"page":"8527-8539","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Measurement Method of Magnetic Field for the Wire Suspended Micro-Pendulum Accelerometer"],"prefix":"10.3390","volume":"15","author":[{"given":"Yongle","family":"Lu","sequence":"first","affiliation":[{"name":"Key Lab. of Opto-Electronic Technology & System, Ministry of Education, Chongqing University, Chongqing 400044, China"}]},{"given":"Leilei","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Lab. of Information Engineering in Surveying, Mapping and Remote Sensing,  Wuhan University, Wuhan 430079, China"},{"name":"College of Aerospace Engineering, Chongqing University, Chongqing 400044, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6444-8467","authenticated-orcid":false,"given":"Ning","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Aerospace Engineering, Chongqing University, Chongqing 400044, China"}]},{"given":"Yingjun","family":"Pan","sequence":"additional","affiliation":[{"name":"Key Lab. of Opto-Electronic Technology & System, Ministry of Education, Chongqing University, Chongqing 400044, China"}]},{"given":"Chunhua","family":"Ren","sequence":"additional","affiliation":[{"name":"Key Lab. of Opto-Electronic Technology & System, Ministry of Education, Chongqing University, Chongqing 400044, China"}]}],"member":"1968","published-online":{"date-parts":[[2015,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"13556","DOI":"10.3390\/s140813556","article-title":"A comprehensive review of sensors and instrumentation methods in devices for musical expression","volume":"14","author":"Medeiros","year":"2014","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"4581","DOI":"10.3390\/s130404581","article-title":"Molecular electric transducers as motion sensors: A review","volume":"13","author":"Huang","year":"2013","journal-title":"Sensors"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"2264","DOI":"10.1007\/s10439-014-1111-8","article-title":"Physiological acoustic sensing based on accelerometers: A survey for mobile healthcare","volume":"42","author":"Hu","year":"2014","journal-title":"Ann.
